X rays of wavelength 0.0196 nm are directed in the positive direction of an x axis onto a target containing loosely bound electrons. For Compton scattering from one of those electrons, at an angle of 145°, what are
(a) the Compton shift (in pm),
(b) the corresponding change in photon energy (in keV),
(c) the kinetic energy (in keV) of the recoiling electron, and
(d) the angle between the positive direction of the x axis and the electron's direction of motion? The electron Compton wavelength is 2.43 x 10-12 m. only part (d),
ocean waves with wavelength 1.2 m and period 1.5s are moving past a pier. a boy runs along the pier, in the direction opposite to the motion of the wave, at 3.5 m/s. how many wave crests pass the boy each second?
An atom of U238 spontaneously decays into two components. One is a small fragment that is ejected with a speed of 1.50x107 m/s, what are the masses of the fission products
A 220 block on a 52 long string swings in a circle on a horizontal, frictionless table at 95.What is the speed of the block? What is the speed of the block.
What was the power of the motor that kept the wheel rotating at 6.5 rev/hr in spite of friction.
what is the potential difference between the plates. A particular freely falling object requires 1.85 s to travel the last 31.0 m before it hits the ground. From what height above the ground did it fall.
To water the yard you use a hose with a radius of 3.50 cm. Water flows from the hose with a speed of 1.10 m/s. If you in part block the end of the hose so the effective radius is now 0.55-cm, with what speed does water spray from the hose.
