Agroup of students perform the same "conservation of mechanical energy" experiment that you performed in lab by allowing a solid sphere and then a solid cylinder to roll down the ramp. both objects were released from the same position at the top of the ramp. if the speed vsphere of the solid sphere at the bottom of the ramp was 1.25 m/s, what would be the speed vcylinder at the bottom of the ramp?

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
