- You stand on top of a skyscraper and drop a rubber ball from a height of 163 m. As the ball bounces off the floor it converts some of its energy into thermal energy -- it becomes warmer. Eventually, it stops bouncing and it has converted all the energy it initially had into thermal energy. How much has its temperature risen? (The specific heat of rubber is 2005 J/(kg*K).)arrow_forwardAn electric shower has a 1.5 kW heating element. (a).How much heat energy can it give out in five minutes? (b).If the element is used to heat 5 kg of water for 5 minutes, what would be the rise in temperature?

If a woman rubs her hands back and forth for a total of 20 rubs, at a distance of 7.50 cm per rub, and with an average frictional force of 40.0 N, what is the temperature increase? The mass of tissues warmed is only 0.100 kg mostly in the palms and fingers. Your answer must have three significant figures and the temperature change in centigrade.arrow_forward
- If you drop a piece of ice on a hard surface, the energy of impact will melt some of the ice. The higher it drops, the more ice will melt upon impact. Find the height from which the a block of ice should ideally be dropped to completely melt if that falls without air drag. [Hint: Equate the joules of gravitational potential energy to the product of the mass of ice and its heat of fusion (in si units, 335,000 J/kg.
