Q1. An x-ray beam with wavelength 0.200 nm is directed at a crystal. As the angle of incidence increases, you observe the first strong interference maximum at an angle 23.50. What is the spacing d between the planes of the crystal?

Q2. A stone has a mass of 5.00 x 10-3 kg and is wedged into the tread of an automobile tire. The coefficient of static friction between the stone and each side of the tread channel is 0.70. When the tire surface is rotating at the maximum speed of 12 m/s stone flies out of the tread. The magnitude FN of the normal force that each side of the tread channel exerts on the stone is 1.8 N. suppose that only static friction supplies centripetal force, and determine the radius r of the tire.
