The object shown is sitting on a horizontal surface and has a mass of 175 kg. If a force of 320 N is applied vertically upward, what is the normal force acting on the object? We will round gravity to 10 m/s^2

Convection currents are caused by differences in what two things?

Why does gravity have a lesser than grater effect on higher altitudes?

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
