A proton is released from rest in a region of space with a nonzero electric field. As the proton moves, describe what happens to the electric potential energy of the system, and to the electric potential that the proton experiences.

Aplane flies directly between two cities, a and b, which are separated by . from a to b, the plane flies into a headwind. on the return trip from b to a, the wind velocity is unchanged. the trip from b to a takes less than the trip from a to b. what is the airspeed of the plane, assuming it is the same in both directions

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

For this car, predict the shape of a graph that shows distance (x) versus time (t). note that time is the independent variable and will be on the bottom axis. need asap
