Can someone help me plzzz !!1! A major camping retailer is marketing a cup that’s made of a composite material. A composite is a combination of materials. In this example, the cup is made of wood and plastic. The retailer says that this material is more durable than plastic and that it won’t break or dent. The material is light, it looks and feels nice, it doesn’t affect taste, and it’s easy to clean. In terms of properties, what’s the value of making composite materials?

Hot air balloons float in the air because of the difference in density between cold and hot air. in this problem, you will estimate the minimum temperature the gas inside the balloon needs to be, for it to take off. to do this, use the following variables and make these assumptions: the combined weight of the pilot basket together with that of the balloon fabric and other equipment is w. the volume of the hot air inside the balloon when it is inflated is v. the absolute temperature of the hot air at the bottom of the balloon is th (where th> tc). the absolute temperature of the cold air outside the balloon is tc and its density is ďc. the balloon is open at the bottom, so that the pressure inside and outside the balloon is the same. as always, treat air as an ideal gas. use g for the magnitude of the acceleration due to gravity.
