The plates of a capacitor are separated by 0.0050 m. The capacitor is charged by a potential difference of 5.0 V and then disconnected. Now you separate the plates to a distance of 0.015 m. What is the new potential difference between the plates?
Using energy considerations, compute the average force the beam exerts on the pile driver while the pile driver is brought to rest.
so hydrogen atoms have a thermal velocity of about 1000 m/s. How does the energy stored in the magnetic field compare with the kinetic energy in a given volume of space.
