Consider these scenarios. Scenario 1- Your ear is resting on the end of a metal bar that is stuck by a drumstick about 7 meters away from your ear.

Scenario 2- You are about 7 meters away from a metal bar that is struck with a drumstick. The sound travels through the air to your ear.

In which of these scenarios would the sound of the drumstick hitting the metal bar get to you in the least amount of time? Explain your answer.

Arrange the images in order to show how lake-effect snow occurs.

Which statement best describes the superposition principle? a.) if two in-phase waves arrive simultaneously at a point, their amplitudes add up b.) if two out-of-phase waves arrive simultaneously at a point, their amplitudes add up c.) if two in-phase waves arrive at a point one after another, their amplitudes add up d.) if two out-of-phase waves arrive at a point one after another, their amplitudes adds up

Asled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slidesa distance d1 down the slope and then covers the distance d2 alongthe horizontal terrain before stopping. find the coefficient ofkinetic friction μk between the sled and the ground, assumingthat it is constant throughout the trip. find the coefficient of kinetic frictionμk. express your answer in terms of someor all of the variables d1, d2, and θ.
