A particle at rest undergoes an acceleration of 1. 7 m/s 2 to the right and 4. 5 m/s 2 up. What is its speed after 7. 2 s? answer in units of m/s.

Chemical energy is a form of energy. a. heat b. kinetic c. potential d. electromagnetic

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e

It is really hard for me right know
