The earth is 1.5 × 1011 m from the sun and takes a year to make one complete orbit. it rotates on its own axis once per day. it can be treated approximately as a uniform-density sphere of mass 6 × 1024 kg and radius 6.4 × 106 m (actually, its center has higher density than the rest of the planet, and the earth bulges out a bit at the equator). using this crude approximation, calculate the following: (a) what is vcm ? (b) what is ktrans ? (c) what is ω, the angular speed of rotation around its own axis? (d) what is krot? (e) what is ktot?

Which statements describe the movement of ocean currents around the globe? check all that apply. strong winds force warm water to sink to the ocean floor. the coriolis effect causes warm and cold water to mix. cool dense water sinks to the ocean floor. warm water replaces cool surface water. wind blowing parallel to the shore causes upwelling of cool water.
