For problems 3,4, and 5, Consider an egg that has a mass of 0.15 kg being held at the top of a flight of stairs. 3. If an egg has 11 J at the top of the stairs, what is the height of the stairs?

4. If the egg is dropped from that height, what is the Kinetic energy right before the egg hits the ground?

5. If the egg is dropped down to the ground from that height, what is the velocity of the egg right before the egg hits the ground?

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object

An electric clothes dryer has a resistance of 8 ohms. it draws 30 a of current. what is the voltage, in volts, of the wall outlet that it is plugged into?

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
