• Derivative Formula Summary

Files: 1

Derivative formula for various types of function in one page, for quick learning

• Question: A man walking with speed 'v' constant in magnitude and direction passes under a ...

Posted in: Physics | Date: 25/05/2016

Let U= speed of shadow

Using the property of similiar triangle.

Speed of shadow(U)  = (V x H) / (H - h)

By similiar triangle property

(U-V)/U = h / H

solving this value of U can be calculated

• Question: What are the advantages and limitations of solar cookers?

Posted in: Physics | Date: 25/05/2016

It uses renewable energy, Creates no pollution

It cant be used during night or rainy season

It cant be used for frying foods

It takes time to cook

• Question: How is corrosion of iron prevented by coating i with a layer of oil?

Posted in: Physics | Date: 25/05/2016

By coating iron with oil protect it from being exposed to atmoshphere. The atmoshpher contains oxygen which is responsible for corrosion. Oxidation reaction takes place when iron surface reacts with oxygen which cause rusting of iron.

• Question: How is infinity concept understood in Mathematics

Posted in: Mathematics,Mathematics,Mathematics,Mathematics,Mathematics | Date: 26/05/2016

In mathematics Infinity means any number devided by 0 equals to infinity

e.g. 1/0 or 2/0 so on.....

• Question: What is meant by corrosion of iron?

Posted in: Physics | Date: 26/05/2016

In chemistry corrosion is defined as the oxidation of any metal surface. So corrosion of iron simply means oxidation of iron

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

Posted in: Mathematics | Date: 26/05/2016

its very simple..

use formulae :-  d / dx(e^U) = e^u X d/dx(U)

so.. Solution : ae^(ax+b)

• Question: What will be the focal length of a lens whose power is given as + 2.0 D?

Posted in: Physics | Date: 27/05/2016

since, Focal length = inverse of power of lense

i.e. F= 1/ P

So, F = 1/ P

= 1/ 2

= 0.5 m

• Question: What is the hindrance in developing wind power and power of water flow?

Posted in: Physics | Date: 01/06/2016

In both the common problem is continuity. Wind  flow is a variable factor also same for the water flow.

So the power generation would be discontinuous and discrete. Aslo there is problem with a constant frequency power which is required by the electrical equipments to work. But this issue can be solved using power electronics circuit.

• Question: Which part of India where wind energy is commercially harnessed?

Posted in: Physics | Date: 01/06/2016

Personally I have seen wind energy plant in Gujarat.

But other states as well have developed that are

Maharashtra

Kerala

West Bengal

J & K

• Question: On what principle does a solar water heater operate?

Posted in: Physics | Date: 01/06/2016

Solar water heater operates on the principle of conservation of energy i.e. energy cant be created cant be destroyed it can transform from one form to other.

So in Solar water heater, Solar energy is converted into heat energy.

• Question: Why does a cut diamond shine more than a glass piece with diamond cut?

Posted in: Physics | Date: 02/06/2016

The refractive index of diamond is more than glass, so the Daimond shines more

• Question: Which type of orbit is suitable for a geostationary satellite?

Posted in: Physics | Date: 02/06/2016

A geostationary satellite is a satellite whose period of rotaion is 24 hr same as that of Earth, So it should follow geosynchronus orbit.

• Question: What is meant by 'critical angle' for a ray of light going from one medium into ...

Posted in: Physics | Date: 02/06/2016

When light travels from denser to rarer medium, the angle of incidence at which angle of  refraction is 90 degree is called critical angle of incidence and increasing beyond that critaical value then light gets reflected to same medium.

e.g. Light travelling in fibre optics

• Question: What are the differences between a natural satellite and an artificial satellite...

Posted in: Physics | Date: 02/06/2016

An artificial satellite is manmade while a natural satellite is nature made. e.g Moon is natural satellite

• Question: Which type of these satellite orbitals will be suitable for collecting data for ...

Posted in: Physics | Date: 02/06/2016

Obviously we all know Geostationary satellite have same time period as of Earth so it can be used for weather forecasting.

Only 3 Geostationary satellite can be used to cover whole earth

• Question: What is meant by 'our universe is expanding'?

Posted in: Physics | Date: 02/06/2016

When scientists talk about the expanding universe, they mean that it has been growing ever since its beginning with the Big Bang. The galaxies outside of our own are moving away from us, and the ones that are farthest away are moving the fastest.
