A roller coaster descends 50.00 m from the top of the ride, to the first low point at the ground level. The roller coaster converts gravitational potential energy to kinetic energy with an efficiency of 60%. What is the velocity of the roller coaster at the first low point?

If the area of a square has increased by a factor of 16, by how much has each side increased?

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
