Power is defined as rate of doing work.
Power= work done/ time taken
Power = energy consumed/ timetaken
Since when work is done, an equal amount of energy is consumed.
S.I unit of power is Watt.
1 watt= 1 joule/ 1 Second.
1 watt is the power of an appliances which consumes energy at the rate of 1 joule per second.

I beams have very high moment of inertia for the same volume of the given material. So they have high stability in case of bending moments. The two horizontal parts (called flanges) of the I beam can bear high bending and shearing stress.
That means they do not get twisted and tilted easily. That is why they are used in girders, and as rails on the railway tracks.

kilowatt hour = 1000watt hour
= 100 × 60 × 60 watt sec
= 3.6 × 10⁶ J [∵ watt = j/s so, watt.sec = j]
hence, kilowatt hour = 3.6 × 10⁶ J
now, electron volt ,eV = 1.6 × 10⁻¹⁹ C.volt
= 1.6 × 10⁻¹⁹ J [ ∵ 1volt = 1J/C so, C.volt = J ]
hence, eV = 1.6 × 10⁻¹⁹ J

Doppler’s Effect
- Doppler Effect is the phenomenon of motion-related frequency change.
- Consider if a truck is coming from very far off location as it approaches near our house, the sound increases and when it passes our house the sound will be maximum. And when it goes away from our house sound decreases.
- This effect is known as Doppler Effect.
- A person who is observing is known as Observer and object from where the sound wave is getting generated it is known as Source.
- When the observer and source come nearer to each other as a result waves get compressed. Therefore wavelength decreases and frequency increases.

In1665, Robert Hooke examined a thin slice of cork and observed that it consists of many little compartments, resembling a honeycomb structure. He made this observation through a self-designed microscope. He termed these boxes as cells, which is a Latin word for ‘a little room".
