Consider a solid cube with a side whose measurement is l and a solid cylinder of diameter d and length h. the cube and cylinder are made of the same material and each generates the same amount of heat. if l-d h, use calculations to determine and state which one, (the cube or the cylinder) that should have a higher heat generation rate

You are driving directly behind a pickup truck, going at the same speed as the truck. a crate falls from the bed of the truck to the road.
