Abox slides across a frozen pond toward the left shore as two children standing on opposite shores pull on the box with ropes. the child on the left shore pulls with a force of 3.0 n, and the child on the right shore pulls with a force of 2.0 n. at a certain instant, the speed of the box is 3.0 m> s.
(a) at that instant, what is the power resulting from each force?
(b) what is the power resulting from both forces?
(c) do your answers to parts a and b change as the box slides? ⦁⦁

The most important difference between a wedge and an inclined plane is a. their size b. their shape c. how they are used d. what they are made of

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts.ki k i = nothing ev request answerprovide feedback
