Audent is trying to answer the question How are electromagnetle and mechanical waves different? Does this data above help answer that question?
O A Yes, it shows that mechanical waves can travel without a medium and electromagnetic waves must have a medium.
OB Yes, it shows that electromagnetic waves move slower when going from ases to liquidato solids, but mechanical waves move faster
OO No, both waves changed speeds with different materials and electromagnetic waves shouldn't change speed as their speed is a constant.
OD. No, the wave speed data does not support a valid difference between electromagnetic and mechanical waves

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.
