A meteorite with a mass of 25 kilograms falls to Earth in a direction perpendicular to the Earthís surface. At t = 0 seconds the meteorite is 1000 meters above the Earth. At
t = 2 seconds it is 750 meters above the Earth. Assume the meteoriteís acceleration
due to gravity is constant during this time. Which of the following is the amount of
work the Earthís gravitational force has done on the meteorite between t O and t =
2?

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
