Answer 1

4) Engine power or horsepower is the maximum power that an engine can put out. It can be expressed in kilowatts or horsepower. The power output depends on the size and design of the engine, but also on the speed at which it is running and the load or torque. Maximum power is achieved at relatively high speeds and at high load.

the unit of power is Watt.

8) 1 unit of energy is equal to 1 kilowatt hour (kWh).

1 unit = 1 kWh

1 kWh = 3.6 x 10^{6} J

Therefore, 250 units of energy = 250 x 3.6 × 10^{6} = 9 x 10^{8} J.
