Area:
• Total Experience:
8 Years
Tutoring Experience :

I have been teaching Biology, Chemistry, Mathematics, Physics to the students of class VII - XII of all boards and I also conduct Spoken English classes for the students willing to speak English effectively and fluently since last seven years. My teaching style is unique it is beneficial for boards as well as language examination.

Tutoring Option :
I Can Manage Both

• ## Question: how to differentiate with respect to x in the given equation y = e ^ (ax + b) wh...

Posted in: Mathematics | Date: 18/12/2015

If y= e^ (ax+b)

taking differentiation of above equation with respect to x

dy/dx= e^(ax+b) * d(ax+b)/dx

dy/dx= a e^(ax+b)

Posted in: Physics | Date: 18/12/2015

For equailateral triange all angles will be 60

Refractive index =sin (A/2)

=sin (60/2)

30

• ## Question: Explain the statement: Half-life of polonium is 3.8 days.

Posted in: Physics | Date: 18/12/2015

Half life of polodium is 3.8 days which means that after 3.8 days polodium will be fall to half of its original value.

• ## Question: In a nuclear reactor, what is the function of graphite rods?

Posted in: Physics | Date: 18/12/2015

In nuclear reactor graphite rods are used as moderator or controller.

Application of moderator is to slow down the newtron and controller is to control the number of neutron.

• ## Question: What is meant by quality factor of an LCR circuit?

Posted in: Physics | Date: 18/12/2015

Q (Quality) factor is defined as the ratio of the resonance frequency and bandwidth.

• Q = 2 pie [ maximum energy stored / energy dissipated per cycle)

• ## Question: Why can’t two independent monochromatic sources of light emitting light of one...

Posted in: Physics | Date: 18/12/2015

Two independent sources of light can never be coherent as the phase difference between them changes quickly and randomly, thus the position of maxima and minima also changes. Thus, there will be general illumination of the screen.

• ## Question: What are the kind of cells present in blood?

Posted in: Biology | Date: 18/12/2015

Cells available in bloods are RBC, WBC and platelets.

• ## Question: State stokes theorem.

Posted in: Electrical | Date: 18/12/2015

Stokes Theorem:

Surface integral of curl of vector field over any surface is equal to the line integral of that vector over the boundary of the surface.

• ## Question: State Gauss's law for electrostatic.

Posted in: Electrical | Date: 18/12/2015

Gauss's Law:

Volume integral of divergence of any vector field taken over a certain volume is equal to the surface integral of vector over the surface enclosing that volume.

• ## Question: Name the metals and alloys for making fuses.

Posted in: Electrical | Date: 18/12/2015

Metals or alloys used in making fuse wire are lead, tinned copper, aluminum or tin lead alloy.

• ## Question: What is pointing vector? What is the significance of pointing vector?

Posted in: Electrical | Date: 18/12/2015

A Poynting vector represents the directional energy flux density of an electromagnetic field, which meeans that it represent the rate of energy transfer per unit area.

SI unit of the Poynting vector is the watt per square metre.

represented as: W/m2

S= E * H

where,

E= Electric field vector

H= Magnetic field vector

• ## Question: What are thermistors?

Posted in: Electrical | Date: 18/12/2015

It is the one type of resostor which depends on temperature.

It varies according to the change in the temperature.

• ## Question: State applications of superconductors.

Posted in: Electrical | Date: 19/12/2015

Applications of superconductors are following:

• electrc motors and generators
• In MRI
• Magnetic Leviation
• Fast fault current limiter
• low-loss power cables

• ## Question: What is a multiplexer?

Posted in: Electronics | Date: 19/12/2015

It is a device that selects one of several analog or digital input signals and forwards the selected input into a single line. It is also known as MUX.

• ## Question: What is meant by polarisation?

Posted in: Electrical | Date: 19/12/2015

polarisation:

It is known as the orientation of the vibration is perpendicular to its mode of propagation.

poloroid material can be used to conduct the phenomenon.

exa: electromagnetic waves ( light waves, sound waves etc)

• ## Question: State the Principle of conservation of energy.

Posted in: Physics | Date: 19/12/2015

Priciple of conservation of energy:

Energy can neither be crated nor be destroyed, it can transfer from one form to another.
