imagine you placed a limestone with a surface area of 1,000 cm2 in a lush, tropical
environment. you also put a quartzite rock with a surface area of 100 cm2 in the desert
climate at a high altitude that experiences various cycles of freezing and thawing
throughout the year. which rock do you think would weather at the fastest rate?
why? your answer should include more than one factor that affects the rate of
weathering

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.
