The speed of the Moon is about 3000 m/s. It is really far away so it doesn’t look like it moves that fast. It has a mass of 7.35 x 10^22 kg and is about 384,390,100 m from the Earth. How much centripetal force is required to make the moon orbit around the Earth?

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.

Which sound characteristic is not affected by the relative motion of an object

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.
