The force required to drag several objects across a floor was measured. Calculate the µK for these objects.

Block Weight Friction µK

A 150 lb 30 lb

B 20.0 N 5.0 N

C 1,500 lb 60 lb

(NOTE: I don't want want you to just give me the answer, I want to know how to work it.)

La olla es de metal por que se calienta mas rápido, y las manijas son de madera por que así no se calientas y tienden a estar mas frías.

The answer is frictional force

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
