Why is the first stage of a large roller coaster usually to take the riders up a large incline assisted by a chain under the roller coaster carts?

A.) To build potential energy which will be turned into kinetic energy throughout the majority of the ride.

B.) To build elastic potential energy which will be transformed throughout the ride.

C.) To build kinetic energy since the ride is starting from rest.

D.) To build suspense, there is no scientific reason.

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
