Glare appears on a computer screen when light from the surroundings reflects off of the screen’s surface. Some computer screens have a special coating to reduce glare. Which best explains how the coating works?
The coating absorbs light that shines on it and prevents the light from reflecting.
The surface of the coating is rough, so light that shines on it gets scattered in many directions.
The coating bends light that passes through it and prevents the light from reaching the user’s eyes.
The surface of the coating allows light from the room to pass through but blocks the light from the screen.

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
