Which of the following correctly describes what power measures? A. the rate at which work is done B. the rate at which energy is lost C. the amount of force used over a distance D. the amount of energy used over a distance
the first question will be, force and distance B
I believe your 2nd question will be B but im not sure.
What is the mechanical advantage of a machine that uses an input force of 20 Newtons to achieve an output force of 60 Newtons? A. 40 B. 4 C. 0.3 D. 3
For the second question I think its D -the amount of energy used over a distance
@evergirl i already told him that answer.
work= B. force and distance
Which of the following correctly describes what power measures? D. the amount of energy used over a distance
What is the mechanical advantage of a machine that uses an input force of 20 Newtons to achieve an output force of 60 Newtons? I think it would be 3.
