A company that makes frying pans needs to create a new substance to coat the pans. The substance must have a high melting point. To create this new substance, workers mixed together two substances that melt at low temperatures in a sealed container. The diagram above shows the repeating groups of atoms that make up the two starting substances. After mixing, the workers found two substances that melt at higher temperatures in the sealed container. (Nothing had escaped.) Which of the diagrams to the left shows the repeating groups of atoms that make up the ending substances?

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.
