Working of Electric Geyser:
</em></u><em>
simply in our homes ,, in electric geysers electric energy is converted into heat energy ,, when cold water enters into the geyser through inlet then it is heated into a container inside the geyser,,when it is heated connection of electricity is cut off inside the geyser,,
</em><em>then this hot water comes out through a outlet ... :)</em>
Answer: The 5 uses of mechanical energy are: 1) Hammering a nail

Edison's education is most unique and relevant.
1. The first teacher he had was his mother
2. He found vital lessons and was influenced greatly by the book of R.G. Parker called School of Natural Philosophy
3. Another educating piece he had was a book entitled The Cooper Union for the Advancement of Science and Art
His style of learning was though reading books on a variety of subjects, a self-educating environment that fosters independent learning which can be useful through his life.
Answer:
Explanation:
Given
Mass of ball is M
Height of incline is H
Here conservation of energy will provide the velocity at bottom
Energy at top of incline plane 
Energy at bottom=Kinetic energy+Rotational energy
Assuming Pure rolling we can write

where
=velocity of ball
=angular velocity of ball
R=radius of ball

where I=moment of inertia of ball



Now ,
