Question

PLEASE HELP! (this is 8th grade physics)

An inventor claims to have built a machine that can produce 120 J of work with an input of 110 J. Would you believe the inventor's claim? Why or why not?

Answer 1

what u say ??

Answer 2

No, the output of work can not be greater than the input.

Answer 3

So the inventor says I can produce 120J from 110J
I say, 'What sorcery is this?'

So he claimed that he got 10J out of nowhere!
Is that possible? Not according to Law of conservation of mass and energy
[I am hoping this is not a nuclear reaction] :D

So, you shouldn't believe the inventor's claim. :)
