Question

que: what is law of conservation of energy.

que: what do you mean by rate of doing work.

need both que's ans​✨

Answer 1

Answer:

Here is ur both questions + answers

1.what is law of conservation of energy?

Similarly, the law of conservation of energy states that the amount of energy is neither created nor destroyed. For example, when you roll a toy car down a ramp and it hits a wall, the energy is transferred from kinetic energy to potential energy.

2.what do you mean by rate of doing work?

Power is the rate of doing work. It is equivalent to an amount of energy consumed per unit time. In the SI system, the unit of power is the joule per second (J/s).

Answer 2

que: what is law of conservation of energy.

The law of conservation of energy states that energy can neither be created nor be destroyed. Although, it may be transformed from one form to another. If you take all forms of energy into account, the total energy of an isolated system always remains constant.

que: what do you mean by rate of doing work.

power

powerThe rate of doing work or rate of transfer of energy is called power. It is represented as Power, P=worktime.
