If an object moving at 12 m/s has a kinetic energy of 72 j what is the mass

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.

What is the fate of the electrons that interact with a specimen in an electron microscope?

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.
