What do radio waves and microwaves have in common? Both have radiant energy than visible light.

Both have lower frequencies than visible light.

Both are at the side of the spectrum that has the highest frequency.

Both have shorter wavelengths than visible light.

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.
