What do we mean by power and energy ? Given their units .

Work and Energy

In nuclear power station energy of uranium is used for producing-

A) Work and energy have the same units in any given system of measurement B) Work and power have the same ratio of SI unit to C.G.S unit

STATEMENT-1: Kilowatt hour is a unit of power STATEMENT-2: Work done energy have same SI units. STATEMENT-3: Dimensions of work is ML^(2)T^(2).

The SI unit of work or energy is joule. Explain why the work and energy have same SI unit.

A wind - powered generator converts wind energy into electrical energy . Assume that the generator convents a fixed fraction of the wind energy intercepted by to blades into electrical energy for wind speed V , the electrical power output will be propertional to

For energy density, power and intensity of any wave choose the correct options.

SI unit of work or energy is joule. _____

In a motor the electrical power input is 500 W and the mechanical power output is 0.54 horse power. Heat developed in the motor in 1 h is (assuming that all the electric energy which is not converted to mechanical energy is converted to heat) is
