Question

1. Have scientists been able to invent a perpetual motion machine?
O Yes
O No

Answer 1

The answer is No
I think this way because of the law of first law of thermodynamics where it says that energy can't be created or destroyed. This means you can’t receive more energy then you put in. In conclusion a machine could only ever produce as much energy as it consumed.

Answer 2

After using my big brain it’s No
