Which of the following is not a unit of energy?a)newton meterb)electron voltc)joule/meterd)kilowatt hourCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

C is correct option because energy The joule ( symbol: J) is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre (1 newton metreor N⋅m). pls upvote and follow me.

Answer

Because dimensions of energy is M1L2T-2 so dimension of options 1,2 and4 matches with it except option 3

Answer

Joule/meter is not a unit of energy, the unit of energy is joule

Answer

Explanation:
Energy is a scalar quantity that is used to describe the ability to do work or cause a change in a system. It is measured in various units, depending on the context.

Newton meter:
The newton meter (N·m) is a unit of energy commonly used in physics and engineering. It is equivalent to one joule (J), which is the SI unit of energy. The newton meter represents the work done when a force of one newton is applied over a distance of one meter.

Electron volt:
The electron volt (eV) is a unit of energy commonly used in atomic and particle physics. It is defined as the amount of energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt. One electron volt is equal to 1.602 × 10^-19 joules.

Joule/meter:
Joule/meter is not a recognized unit of energy. It is a combination of the joule (J), which is a unit of energy, and the meter (m), which is a unit of distance. Dividing energy by distance does not result in a valid unit of energy.

Kilowatt hour:
The kilowatt hour (kWh) is a unit of energy commonly used in the context of electricity consumption. It is equivalent to the amount of energy consumed by a device with a power of one kilowatt (kW) over a period of one hour. One kilowatt hour is equal to 3.6 × 10^6 joules.

Conclusion:
Among the given options, the unit 'joule/meter' is not a valid unit of energy. It is important to note that energy units should be standalone and not a combination of other units. The correct units of energy are newton meter (N·m), electron volt (eV), and kilowatt hour (kWh).
