If a body with a mass of 4 kg is moved by a force of 20 N, what is the rate of its acceleration?

A beam of light is propagating in the x direction. The electric-field vector (a) can oscillate in any arbitrary direction in space. (b) must oscillate in the z direction (c) must oscillate in the yz plane (d) must oscillate in the x direction.

a ray of light emerging from glass into air is incident at the critical angle of the glass block what is the angle of refraction in the air

What will occur when the trough of Wave A overlaps the trough of Wave B? A: Destructive interference will occur, causing the new wave to have more energy than Wave A or Wave B.
