You are skating down a hill with no means of measuring velocity: You can measure however, that the downhill distance is 100 m and it takes 10 s to rerch the bottom. If you begin with a 0.5 m/s velocity what will the final velocity at the bottom of the
hill be?

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 =
