Which of the following quantities have same unit a.power and energy b....
Explanation:
Power:
Power is the rate at which work is done or the rate at which energy is transferred or converted. It is measured in watts (W). Power can be calculated using the formula:
Power = Work / Time
Energy:
Energy is the ability to do work. It is measured in joules (J). Energy can be classified into different forms such as kinetic energy, potential energy, thermal energy, etc.
Work:
Work is done when a force is applied to an object and it moves in the direction of the force. It is measured in joules (J). Work can be calculated using the formula:
Work = Force x Distance
Comparison of Units:
Power and Energy:
Power and energy do not have the same unit. Power is measured in watts (W), while energy is measured in joules (J). They cannot be equated or compared directly.
Work and Energy:
Work and energy have the same unit, which is joules (J). This is because work is the transfer of energy. When work is done on an object, energy is transferred to that object. Therefore, work and energy are directly related and can be equated.
Power and Work:
Power and work do not have the same unit. Power is measured in watts (W), while work is measured in joules (J). They cannot be equated or compared directly.
Conclusion:
Among the given options, the correct one is "none of these" (d) because power and energy, power and work, and work and energy do not have the same unit. The units for power, energy, and work are distinct and cannot be interchanged or compared directly.
Which of the following quantities have same unit a.power and energy b....
Work and energy have the same unit which is taking by Joule.
The force between Newton and energy joule can be calculated. Energy Joule, Force newton, energy Joule, works Joule.
Therefore option b is correct.
