An X-ray beam of wavelength 0.01nm strikes a target containing free electrons. Consider an x-ray scattered from the target at an angle of 180deg. Determine:
a) The change in wavelength of the scattered x-ray.
b) The change in photo energy between the incident and scattered x-ray.
c) The kinetic energy transferred to an electron.
d) the electron's direction of motion (assuming it was initially stationary).
A point particle that has a charge of 18.5 µC is located at x = 0, y = 0 and a point particle that has a charge q is located at x = 14.8 cm, y = 0. The electric force on a point particle that has a charge of 7.4 µC at x = 29.6 cm, y = 0 is -(19.7)..
Use gauss law to find the electtic field E from a spherical +charged sphere of radius r
A capacitor should have charge of magnitude 4.5 microC on each plate, and an electric field of 2.0 kV/mm between the plates
What is the electric force

A boat has a mass of 6800 kg. Its engines generate a drive force of 4000 N, find the magnitude and direction of the boat's acceleration
A string vibrates in five segments to a frequency of 460Hz. (a) what is its fundamental frequency? (b) What frequency will cause it to vibrate in three segments.
A 9.10 kg board is wedged into a corner and held by a spring at a 50° angle, as the Illustrating shows. The spring has a spring constant of 196 N/m and is parallel to the floor.
A large wood block is being pushed across the floor with a force of 180-N to the right. The block has a mass of 145.00 kg. The frictional force is 45-N. What is the acceleration of the block.
Two cars travel in the same direction along a straight highway, one at a constant speed of 55 mi/h and the other at 70 mi/h. How far must the faster car travel before it has a 15-min lead on the slower car
A 5.4-µC point charge is located at x = 0.9 m, y = 3.3 m, and a -3.9-µC point charge is located at x = 1.9 m, y = -1.9 m. (a) Find the magnitude and direction of the electric field at x = -3.2 m, y = 0.9 m.' (b) Find the magnitude and direction of..
