Asmall metal sphere has a mass of 0.12 g and a charge of -24.0 nc. it is 10.0 cm directly above an identical sphere that has the same charge. this lower sphere is fixed and cannot move. if the upper sphere is released, it will begin to fall. part a what is the magnitude of its initial acceleration?

Your pendulum clock which advances 1.0 s for every complete oscillation of the pendulum is running perfectly on earth at a site where the magnitude of the acceleration due to gravity is 9.80 m/s2. you send the clock to a location on the moon where the magnitude of the acceleration due to gravity is 1.65 m/s2.

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds
