How is the weight of an object in a spaceship near the moon related to the distance that the spaceship is from the moon? a) there is is no gravity on the moon and therefore they are not related. b) as the distance to the moon decreases, the weight of the spaceship would increase. c) as the distance to the moon increases, the weight of the spaceship would increase. d) the gravitational pull of the moon is constant and therefore the weight would be a constant.

The movement of electrons between atoms is called an

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
