An object weighs 100 N on the surface of the earth. Find its weight if it was 6.38 x 10' m above the surface?

Astone dropped into a well is heard to strike the water after 8seconds. find the depth of the well if the velocity of sound is 350m/s

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

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.
