Two balls of equal masses, one at rest, the other moving with a speed V directly toward the other. Assuming the collision is partially elastic with a coefficient of restitution of 0.8, what final velocities, in terms of V, would the two balls end up with

What is the fate of the electrons that interact with a specimen in an electron microscope?

True or false: the cycle of seasons on the earth is caused by the tilt of the earth on its axis toward and away from the sun.

Use the profile illustrated for problem (1). assume that the layer of silty sand fill (sm) is placed over the entire site. estimate the thickness of the fill (h - in feet) that will cause the effective vertical stress at the center of the clay layer to increase by 517.5 pounds per square foot.
