Question

How the law of conservation of energy is applied for vacuum cleaner?

Answer 1

Answer:

hey mate here is your answer:

Vacuum energy is an underlying background energy that exists in space throughout the entire Universe. This behavior is codified in Heisenberg's energy–time uncertainty principle. Still, the exact effect of such fleeting bits of energy is difficult to quantify. The vacuum energy is a special case of zero-point energy that relates to the quantum vacuum

I hope this would help you

thank you :)

Answer 2

According,to the law of conservation of energy,the amount of energy in a closed system always stay constant. So,the amount of work output and other transformed energy is equal to the amount of energy inputs. • In this way,the conservation of energy is fulfilled by the machines.
