An X-ray photon with a wavelength of 0.260 nm scatters from a free electron at rest. The scattered photon moves at an angle of 105° relative to its incident direction.
Find the initial momentum of the photon.
Find the final momentum of the photon.
Assuming that the Earth is spherical and recalling that latitudes range from 0° at the Equator to 90° N at the North Pole, how far apart, measured on the Earth's surface
The potential difference between two points in a wire 10 m apart is 12 V. When the current density is 4*10^7 A/m^2. find the resistivity of the material in the wire
Two large, parallel, conducting plates are 26cm apart and have charges of equal magnitude and opposite sign on their facing surfaces. An electrostatic force of 2.8 x10-15 N acts on an electron placed anywhere between two plates.
A small piston with area A1 = 45 cm^2 acts in a cylinder to lift a larger piston A2 = 550 cm^2 Find the force on the small piston (F1) if the pressure in the system is 7000 pascals.

As a 13,800 kg jet plane lands on an aircraft carrier, its tail hook snags a cable to slow it down. what was the plane's landing speed
A 3.08 kg block starts from rest at the top of a 30° incline and accelerates uniformly down the incline, moving 2.13 m in 1.60 s. Find the magnitude of the frictional force acting on the block
To demonstrate the tremendous acceleration of a top fuel drag racer, you attempt to run your car into the back of a dragster that is "burning out" at red light before the start of a race. (Burning out means spinning the tires at high speed to heat..
a car initially running at 10 m/s applies brake and stops in 10 secs. What is the deceleration produced by the brakes
define the potential difference between the plates.With what force must the player push the puck so that his force just equals the frictional force.
Object O1 is 15.2 cm to the left of a converging lens with a 11.8-cm focal length. What is the nature (i.e., real or virtual, upright or inverted) of the final image
