Please help will give brainliest :) Someone made a copy of an analog wave and a digital wave. Compare the copies with the original waves. Then, explain which type of wave is a more reliable way to encode and transmit information.

Aray diagram for a refracted light day is shown. what does the dashed line represent

Acar travels along a highway with a velocity of 24 m/s, west. the car exits the highway; and 4.0 s later, its instantaneous velocity is 16 m/s, 45° north of west. what is the magnitude of the average acceleration of the car during the four-second interval?

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.
