Calculate the electric potential energy in a capacitor that stores 1.0 * 10 ^ - 10 of charge at 100.0v

The potential in a region between x = 0 and x = 6.00 m is v = a + bx, where a = 14.0 v and b = -7.30 v/m.

An astronomer at the equator measures the doppler shift of sunlight at sunset. from this, she calculates that earth’s tangential velocity at the equator is 465 m/s. the centripetal acceleration at the equator is 3.41  10 2 m/s 2 . use this data to calculate earth’s radius.

Acurve connects the data points that are plotted. (physical science chapter 11 motion)
