A man stands on the roof of a 18.0-m-tall building and throws a rock with a velocity of magnitude 30.0 m/s at an angle of 37.0 â above the horizontal. You can ignore air resistance. Assume that the rock is thrown from the level of the roof. Calculate the magnitude of the velocity of the rock just before it strikes the ground.

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
