Which item rotates in a magnetic field as an electric motor produces kinetic energy. A. Lightbulb

B. Loop of wire

C. Battery

D. Permanent magnet

What are the differences and similarities of a compression wave and a transverse wave?

Write short note on the following ; collision theory, rotation angle and angular velocity, centripetal acceleration, coriolis force, and newton's law of gravitation.

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?
