A proton travels at a speed of 2.0 * 106 meters/second. Its velocity is at right angles with a magnetic field of strength 5.5 * 10-3 tesla. What is the magnitude of the magnetic force on the proton?

What is it called when light passes through an object

A 0.0220 kg bullet moving horizontally at 400 m/s embeds itself into an initially stationary 0.500 kg block. (a) What is their velocity just after the collision? (b) The bullet-embedded block slides 8.0 m on a horizontal surface with a 0.

If the speed of an object is tripled, its kinetic energy will be

An electric dipole with its center located at the origin of a Cartesian coordinate system oscillates along the x axis, creating an electromagnetic wave.

What are the differences between concave and convex lenses and mirrors?

Electricity problem (coulomb's law)

An observer (O) spots a plane (P) taking off from a local airport and flying at a 29° angle horizontal to her line of sight and located directly above a tower (T). The observer also notices a bird (B) circling directly above her.

In order for convection to occur, you must have
