In Example Suppose the rod stays on the wall in the same position, but the hinge is moved to be at the center of mass position of the rod. The rod is then held out horizontally and released. How do the energiesof the system change after the rod is released? Check all that apply.
a. The change in the system’s gravitational potential energy would be zero
b. The change in the system’s gravitational potential energy is positive
c. The change in the system’s gravitational potential energy is negative
d. The change in the system’s kinetic energy would zeroThe change in the system’s kinetic energy is positive
e. The change in the system’s Kinetic energy is negative

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
