Location x and y are adjacent. location x has a lower air pressure than location y. what will most likely happen? wind will blow from one location to another. air above location y will rise up and condense. temperature at the two locations will become equal. convection currents of air above the two locations will stop.

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.
