You want to close an open door by throwing either a 400-g lump of clay or a 400-g rubber ball toward it. you can throw either object with the same speed, but they are different in that the rubber ball bounces off the door while the clay just sticks to the door. which projectile will apply the larger impulse to the door and be more likely to close it and why?

Consider the growth of a 20-nm-diameter silicon nanowire onto a silicon wafer. the temperature of the wafer surface is maintained at 2400 k. assume the thermal conductivity of the silicon nanowire is 20 wm-1k-1 and all its surfaces including the tip are subjected to convection heat transfer with the coefficient h = 1×105 wm-2k-1 and t∞ = 8000 k. when the nanowire grows to l = 300 nm, what is the temperature of the nanowire tip (t (x =
