Question

State whether the statement is true or false. If false, rewrite the correct form of the statement

A machine can raise a heavy load without the supply of any energy to it.

• A. True
• B. False

Answer 1

The correct option is B False

1. Energy is required to raise the heavy load by the machine.
2. Machine works on the principle that when we do some work on the machine in form of input machine gives out this work in the form of output. So any work done by the machine requires energy.

Hence the given statement is false.
