Answer
Answer
  • Answer:

    Do you know how a building is constructed? They first create building blocks(bricks etc) and then join them to make a wall and join the walls to make a room.  Knowledge building is exactly same. Lets take chapter 7 of your NCERT book "Motion and Time". First thing you need to undertand is what motion is.  Do not move forward until you understand that completely. Similarly you cannot understand velocity until you finish distance and displacement. Keep asking questions  until you are fully satisfied be it your teacher, tutor, parents or classmates anyone. Try to relate it to your day to day activities.  Lets say you play cricket. You spin the ball its rotation and then its reaching the batsman in linear motion so its rotation and linear motion at the same time.  And as you said that you "love" science it wont be difficult for you to do that.  Anyone can learn anything provided they work hard and of course a proper guidance is icing on cake.       WHY and HOW, Make these two words your best friends, everything will be easy. Keep working hard and all the best.

  • Question: What is bell metal?

    Posted in: History | Date: 20/02/2018

    Answer:

    Bell metal is an alloy of copper and tin (a type of bronze) with high tin content of 20-25%. The higher tin content increases the rigidity of the metal, and increases the resonance which is why it is used for making bells and related instruments, such as cymbals, hence the name bell metal. 

     

     

  • Question: What is bronze?

    Posted in: History | Date: 20/02/2018

    Answer:

    Bronze is an alloy that consists primarily of copper with the addition of other ingredients. In most cases the ingredient added is typically tin, but arsenic, phosphorus, aluminum, manganese, and silicon can also be used to produce different properties in the material. All of these ingredients produce an alloy much harder than copper alone.

    Bronze is characterized by its dull-gold color.

    Bronze is used in the construction of sculptures, musical instruments and medals, and in industrial applications such as bushings and bearings, where its low metal on metal friction is an advantage. Bronze also has nautical applications because of its resistance to corrosion.

  • Question: Is Biogas a biofuel?

    Posted in: Chemistry | Date: 20/02/2018

    Answer:

    Biogas is a biofuel produced from the anaerobic fermentation of carbohydrates in plant material or waste (eg food peelings or manure) by bacteria.

    It is mainly composed of methane, with some carbon dioxide and other trace gases. However, the proportion of methane within the biogas can vary between 50% and 80%, depending on whether some oxygen is able to enter at the beginning or during the process. If some oxygen is present, the bacteria will respire aerobically and will produce a gas with a higher proportion of carbon dioxide and a lower proportion of methane.

  • Question: What is a magnitude of a vector?

    Posted in: Physics | Date: 20/02/2018

    Answer:

    To put it simply it is just the size of the vector. All vectors have two components: magnitude and direction. For example, weight is a vector. A 200lb man exerts a force of 200lbs (which is the magnitude) in the downward direction.

    If shortest distance between your home and school is 5kms then the magnitude of your displacement is 5kms and the direction is home to school. 

    The magnitude of a vector defines its length. Vector magnitude is expressed as the distance between its initial point (vector tail) and terminal point (vector head). 

  • Question: What is the formula for acceleration?

    Posted in: Physics | Date: 20/02/2018

    Answer:

    Acceleration, is the rate of change of velocity of an object with respect to time. However this is a very generic definition mostly apt for average acceleration. 

    You started from home your bus stopped for you then increased its speed and when it reached school it stopped again. If you try to calculate acceleration between these two points using formula (final velocity - initial velocity)/ time what are you going to get??

    Think about it and research further.

  • Question: Can you have a negative magnitude of acceleration?

    Posted in: Physics | Date: 20/02/2018

    Answer:

    Magnitude of any vector qualntity is always positive. It basically repsents the size of the vector.

  • Question: What is the Atlantic Charter?

    Posted in: History | Date: 20/02/2018

    Answer:

    The Atlantic Charter was a pivotal policy statement issued during World War II on 14 August 1941, which defined the Allied goals for the post world war. The leaders of the United Kingdom and the United States drafted the work and all the Allies of World War II later confirmed it. The Charter stated the ideal goals of the war—no territorial aggrandizement; no territorial changes made against the wishes of the people, self-determination; restoration of self-government to those deprived of it; reduction of trade restrictions; global cooperation to secure better economic and social conditions for all; freedom from fear and want; freedom of the seas; and abandonment of the use of force, as well as disarmament of aggressor nations. Adherents of the Atlantic Charter signed the Declaration by United Nations on 1 January 1942, which became the basis for the modern United Nations.

  • Question: When the dot product of two vectors is 0?

    Posted in: Physics | Date: 20/02/2018

    Answer:

    The dot product of A and B is the length of the projection of A onto B multiplied by the length of B. 

    If A and B are orthogonal/ perpendicular  to each other the projection of one onto another would be zero so is the dot product. 

  • Question: What is the unit for the magnitude of acceleration?

    Posted in: Physics | Date: 20/02/2018

    Answer:

    Velocity is rate of change of displacement with respect to time. -> displacement/ time

    Average acceleration is rate of change of velocity with respect to time. -> velocity / time

    which is (displacement / time ) / time the unit would be unit of displacement / (unit of time x unit of time )

    Now it depeds you are using which system, S.I MKS or CGS based on which it would be meter/ second ^ 2 etc.

    The release of too much thyroxine in the bloodstream is known as thyrotoxicosis. This may be caused by overactivity of the thyroid gland (hyperthyroidism), as in Graves' disease, inflammation of the thyroid or a benign tumour. Thyrotoxicosis can be recognised by a goitre, which is a swelling of the neck due to enlargement of the thyroid gland. 

  • Question: What gland controls blood sugar levels?

    Posted in: Biology | Date: 05/03/2018

    Answer:

    The pancreas is a glandular organ in the upper abdomen, but really it serves as two glands in one: a digestive exocrine gland and a hormone-producing endocrine gland. Functioning as an exocrine gland, the pancreas excretes enzymes to break down the proteins, lipids, carbohydrates, and nucleic acids in food. Functioning as an endocrine gland, the pancreas secretes the hormones insulin and glucagon to control blood sugar levels throughout the day.

  • Question: Which hormone is a peptide?

    Posted in: Biology | Date: 05/03/2018

    Answer:

    The three types of hormones are steroid hormones, peptide hormones and amino acid derivatives

    • Peptide hormones are hydrophylic and lipophobic (fat-hating) – meaning they cannot freely cross the plasma membrane
    • They bind to receptors on the surface of the cell, which are typically coupled to internally anchored proteins (e.g. G proteins)
    • The receptor complex activates a series of intracellular molecules called second messengers, which initiate cell activity
    • This process is called signal transduction, because the external signal (hormone) is transduced via internal intermediaries
    • Examples of second messengers include cyclic AMP (cAMP), calcium ions (Ca2+), nitric oxide (NO) and protein kinases
    • The use of second messengers enables the amplification of the initial signal (as more molecules are activated)
    • Peptide hormones include insulin, glucagon, leptin, ADH and oxytocin

  • Question: Which hormone controls blood sugar levels?

    Posted in: Biology | Date: 05/03/2018

    Answer:

    Insulin

  • Question: What do the hormones do?

    Posted in: Biology | Date: 05/03/2018

  • Question: What are the four types of hormones?

    Posted in: Biology | Date: 05/03/2018

    Answer:

     

    There are four types of hormones in most vertebrates. They are grouped by the chemicals from which they are made.

    • Steroid hormones – these are made from cholesterol. 
    • Eicosanoids: these are lipid hormones – hormones made from lipids, kinds of fats. These are mostly hormones that send messages near the cell that makes the hormones.
    • Amino acid derived. Melatonin works on the brain, and thyroxine acts on almost all cells in the body. Many of these hormones are neurotransmitters, hormones that one nerve cell sends to another nerve cell.
    • Peptides, polypeptides and proteins – small peptide hormones include TRH and vasopressin. Peptides composed of scores or hundreds of amino acids are referred to as proteins.

  • Question: Explain Antiferromagnetism:

    Posted in: Chemistry | Date: 13/03/2018

    Answer:

    Antiferromagnetism, type of magnetism in solids such as manganese oxide (MnO) in which adjacent ions that behave as tiny magnets (in this case manganese ions, Mn2+) spontaneously align themselves at relatively low temperatures into opposite, or antiparallel, arrangements throughout the material so that it exhibits almost no gross external magnetism. In antiferromagnetic materials, which include certain metals and alloys in addition to some ionic solids, the magnetism from magnetic atoms or ions oriented in one direction is canceled out by the set of magnetic atoms or ions that are aligned in the reverse direction.

  • Question: Explain Ferrimagnetism:

    Posted in: Chemistry | Date: 13/03/2018

These modifiers (also known as type qualifiers) are the keywords that alter either size or range or both of the data types. The various modifiers are short, long, signed and unsigned. By default the modifier is signed.

  • Answer:

     A reference variable is an alias, that is, another name for an already existing variable. Once a reference is initialized with avariable, either the variable name or the reference name may be used to refer to the variable.

     

    // declare simple variables int i;

    double d;

    // declare reference variables

    int& r = i;

    double& s = d;

  • Answer:

    A constant, like a variable, is a memory location where a value can be stored. Unlike variables, constants never change in value. You must initialize a constantwhen it is created. C++ has two types of constants: literal and symbolic. A literalconstant is a value typed directly into your program wherever it is needed.

  • Question: What is meant by reference variable in C++?

    Posted in: C,C++ | Date: 13/03/2018

  • Question: What is Extern Storage Class ?

    Posted in: Programming Language | Date: 13/03/2018

    Answer:

    The extern storage class is used to give a reference of a global variable that is visible to ALL the program files. When you use 'extern', the variable cannot be initialized however, it points the variable name at a storage location that has been previously defined.

    When you have multiple files and you define a global variable or function, which will also be used in other files, then extern will be used in another file to provide the reference of defined variable or function. Just for understanding, extern is used to declare a global variable or function in another file.

  • Answer:

    7:32 is the ratio of their no of molecules.

  • Answer:

    A semiconductor material has an electrical conductivity value falling between that of a conductor – such as copper, gold etc. – and an insulator, such as glass. Their resistance decreases as their temperature increases, which is behavior opposite to that of a metal. Their conducting properties may be altered in useful ways by the deliberate, controlled introduction of impurities ("doping") into the crystal structure. Where two differently-doped regions exist in the same crystal, a semiconductor junction is created. The behavior of charge carriers which include electrons, ions and electron holes at these junctions is the basis of diodes, transistors and all modern electronics.

  • Answer:

    An electrostatic field line is constructed  to visualize an electric field and the effect it has on charges. It emerges out of a positive charge and sink up at the negative charge. A single field line gives the direction and the path in which a unit positive charge would move if placed at any point along that line. These lines are assumed to be continuous and travel to infinity, because, their discontinuity would mean that the charge has suddenly vanished and reappears again, which is absurd.

  • Answer:

    Cloud is a huge concentration of water vapour in the air. Rain gets triggered when the air becomes very cold and the water vapour gets converted in small water droplets. These small water droplets attach to each other and become bigger water droplets which cannot remain suspended in air and therefore, fall on the earth in the form of rain.

    Cloud seeding, an artificial process of making rain is done by precipitation, a process of condensation of water vapours in the air. This is done by using cloud seeding chemicals like potassium  iodide, silver iodide, liquid propane or solid carbon dioxide(dry ice).  These cloud seeding chemicals are seeded in the clouds through manned aircrafts, remote controlled rockets or other dispersion devices stationed on the ground.

  • Question: What is the role of an inductor in a circuit?

    Posted in: Physics | Date: 15/03/2018

    Answer:

    An Inductor is a passive device that stores energy in its Magnetic Field and returns energy to the circuit whenever required. An Inductor is formed by a cylindrical Core with many Turns of conducting wire.

    When current first starts flowing in the coil, the coil wants to build up a magnetic field. While the field is building, the coil inhibits the flow of current. Once the field is built, current can flow normally through the wire. When the switch gets opened, the magnetic field around the coil keeps current flowing in the coil until the field collapses. This current keeps the bulb lit for a period of time even though the switch is open. In other words, an inductor can store energy in its magnetic field, and an inductor tends to resist any change in the amount of current flowing through it.

    Because of above charecteristics inductors are used as chokes. i.e to block AC and allow DC to pass. 

     

  • Question: How can power loss be reduced?

    Posted in: Physics | Date: 19/03/2018

    Answer:

    The question is too. Assuming that we are talking about electric transmission here. Below are the methhods used to reduce power loss. 

    High transmission voltage: 

    To reduce energy loss, electricity generated in power stations is raised to a very high voltage for transmission. A high transmission voltage means only a relatively small current flows through the transmission cables. As you know, current produces heating effect when flowing through the cables with resistance. When the current used for transmission is small, energy loss due to heating effect on the cables is reduced, enabling more electrical power to be transferred to the users.

    Low resistance transmission wires

    As the heating effect occurs when a current flows through cables with resistance, reducing the resistance of the transmission cables will reduce energy loss. Copper and aluminium are the most commonly used metals in transmission wires. They are very good conductors, cheap, resistant to corrosion, and strong. The resistance of the transmission wire is lowered by making the wire thicker. Thicker wires have larger cross-sectional area and therefore lower resistance.

     

  • Question: What is the Magnocellular?

    Posted in: Physics | Date: 19/03/2018

    Answer:

    ‘Magnocells’ or M-cells carry visual neural information along the upper, dorsal stream of the brain to help us understand motion. This magnocellular visual pathway tells us all about the ‘where’ of things: WHERE objects exist in relation to ourselves and HOW we guide our movement in relation to those objects, but not what they look like. The magnocellular visual stream signals us to an awareness of the time properties of objects. For instance, detection of the movement, distance, and speed of an object moving towards us.

  • Question: What is a Microarray?

    Posted in: Bio-medical | Date: 19/03/2018

    Answer:

    A microarray is essentially, an ordered array of DNA or any nucleic acids. It’s typically gridded out onto some kind of solid support, so that, basically in a very small area, let’s say a microscope slide, you can put down every single gene in the genome, forty, fifty-thousand genes in that small area. And you can basically then, in a very quick hybridization experiment, if you label, let’s say, different patients or different people's DNA, you can hybridize them on and basically measure, with fluorescent signal, how much of each DNA is binding to each part of the genome. So in basically one step, in a few hours or in twenty-four hours, you can assess the entire genome of an individual or a species for changes in copy number, for changes in expression, etc. So, essentially what it has done is given us the ability, rather than looking one gene at a time at specific things or a few genes at a time, to be able to look at the whole system of the genome in parallel. So it really has brought us into this area of genome systems biology. So we can look at the entire genome of an individual or a person or a treatment or anything, kind of at once, very, very efficiently and very cheaply now.
