The charge on an electron is

Asap and show ! a 14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.

What are the similarities & differences between a thermistor and a light dependent resistor in physics?

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.
