Light of wavelength 485 nm passes through a single slit of width
8.32 x 10-6 m. What is the angle
between the first (m = 1) and second
(m = 2) interference minima?

Which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.

Which body is in equilibrium? (1) a satellite orbiting earth in a circular orbit (2) a ball falling freely toward the surface of earth (3) a car moving with a constant speed along a straight, level road (4) a projectile at the highest point in its trajectory
