Consider two point particles that have charge +e, are at rest, and are separated by 1.10 x 10-15 meter. The mass of each particle is 1.00 u (1.00 amu). Determine what speed will each have when they are very far from each other
You can estimate the distance to a lightning flash by counting the seconds that elapse between the time you see the flash and when you hear the accompanying thunder. The approximate distance in miles is obtained by dividing the time in seconds by 5..
