Abeam of electrons passes through an electric field where the magnitude of the electric field strength is 3.00 * 10^3 newtons per coulomb. what is the magnitude of the electrostatic force exerted by the electric field on each electron in the beam?

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

What are similarities and differences between refraction, reflection, diffraction and absorption?

What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?
