A diver comes off a board with arms straight up and legs straight down, giving her a moment of inertia about her rotation axis of 18 kg⋅m2. She then tucks into a small ball, decreasing this moment of inertia to 3.6 kg⋅m2. While tucked, she makes two complete revolutions in 1.2 s.

If she hadn't tucked at all, how many revolutions would she have made in the 1.5 s from board to water?

Which of these statements best explains how the hydrosphere interacts with the atmosphere to affect global climate? mountains block rain clouds and cause changes in global rainfall and evaporation. humans burn fossil fuels to produce greenhouse gases which cause global warming. humans cut down trees which affects the amount of oxygen in different parts of the globe. greenhouse gases, like carbon dioxide, dissolve in oceans and prevent global warming.
