What is the momentum if the mass is 120
kg and the velocity is -7m/x?

Use the table to answer question 22 23 and 24.

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

What’s #16 asking and how do i solve it?
