X rays with a wavelength of 0.21 nm undergo first-order diffraction from a crystal at a 52∘ angle of incidence. At what angle does first-order diffraction occur for x rays with a wavelength of 0.14 nm? Express your answer in degrees.

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
