59. Conduction is A) the direct transmission iof energy without the need for a medium of transfer. B) the transfer of heat via bulk motion of the medium. C) the transfer of heat by electron and atomic collisions. D) the only way to transfer heat from a colder object to a warmer ones. 60. Convection is A) the direct transmission of energy without the need for a medium of transfer. B) the transfer of heat via bulk motion of the medium. C) the transfer of heat by electron and atomic collisions. D) the only way to transfer heat from a colder object to a warmer ones. 58. When you touch the metal handle of the room -temperature stainless-steel frying pan, it feels cool to your touch. When you grab a room-temperature sauce pan by its plastic handle, A) it feels cooler than the metal handle because plastic conducts heat better than the metallic steel. B) it feels warmer than the metal handle because the steel handle conducts heat better than the plastic. C) it doesn't feel cooler or warmer than the steel. Why would it? Both handles are at room temperature! 2 points 2 points 2 points

That previous shot was a bust and the player tries for a second shot. This time they throw the ball at $8m/s$ with a 45 degree angle. The height of the throw is 2.4 m above the floor and the hoop is 3.1 m tall. How long will the ball be in the air before reaching the height of the hoop? (hint:we've done this in examples and there are two ways of doing it) 8.11 sec 0.63 sec 0.12 sec 1.01 sec 1.35 sec 5.31 sec
