Seen through a traditional optical telescope, the space between stars and galaxies is pitch black. but, with a radio telescope, we detect a faint background glow, almost exactly the same in all directions, that is not associated with any star, galaxy, or other object. this phenomenon, which provides evidence for the big bang theory, is called the

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.
