Assume the bowling ball has an initial temperature of 0 degreesC, and that no water or ice splashes out.
Draw a schematic diagram of a Michelson interferometer. Describe a setup that allows a pattern of circular interference fringes, localised at infinity
A stationary block explodes into two pieces that slide along a frictionless floor and then into regions with friction, where they stop.
Describe what happens in the retina (at the cellular level) when you "get used to the dark. Why is it not possible to see color at night?
Three identical loudspeakers play a 170 Hz tone in a room where the speed of sound is 340 m/s. You are standing 4 m in front of the middle speaker
Show that the kinetic energy K and the momentum magnitude p of a particle of mass m are related by K = p2/2m.
Determine the speed of the rod's center of mass just before it hits the surface. Use h, M, and g for length, mass, and gravitational acceleration.
You are standing 2.2 m from a 150 W light bulb.
A pendulum consists of a string of length L and a bob of mass M. The string is brought to a horizontal position and given the minimum initial speed.
The light that passes though has an intensity of 50% of the incident beam. The angle between the direction of the polarization of the incident beam
On a frictionless horizontal air table, puck A (with mass 0.369 ) is moving toward puck B (with mass 0.249 ), which is initially at rest.
Consider a point source of light. How would the intensity of light vary with distance from the source according to a) wave theory
Cold, interstellar, molecular clouds have been seen to contain the cynogen molecule, CN, whose first rotational excited states have an energy.
Twenty violins playing simultaneously with the same intensity combine to give an intensity level of 82.5 dB.
A pair of bumper cars in an amusement park ride collide elastically as one approaches the other directly from the rear.
Sound 1 has an intensity of 380.0 W/m^2. Sound 2 has an intensity level that is 2.5 dB greater than the intensity level of sound 1
Two converging lenses with focal lengths of 40cm and 20cm are placed 10cm apart. A 2cm tall object is 15cm from the 40cm focal length lens.
A 0.420 kg ice puck, moving east with a speed of 3.04 m/s, has a head-on collision with a 0.930 kg puck initially at rest.

The potter can stop the wheel in 6.00 s by pressing a wet rag against the rim and exerting a radially inward force of 65.0 N.
Unpolarized light passes through two polaroid sheets. The axis of the first is vertical, and that of the second is at 26.0° to the vertical.
What is the mass of a man running at 5 m/s if he has a kinetic energy of 500 J?
This figure indicates the energy required to conjure up the rabbit "out of thin-air". Evidently it takes more than energy, U=E, of the rabbit.
Calculate the speed of the ball as it leaves the barrel if a constant resisting force of 6.00 N acts on the ball as it moves along the barrel.
