In the above picture, suppose the rod were made of solid glass instead of solid aluminium. Which statement is correct?
Glass is a good conductor so glog A melts faster
Glass has particles that can flow, so the wax melts by convection
Glass is a good insula on to the wax would not melt
Glass allows radiation to pass though it so the wax would melt slower

The most efficient way to establish the best possible economizer position is to measure

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
