An elite Tour de France cyclist can maintain an output power of 430 W during a sustained climb. Part A At this output power, how long would it take an 87 kg cyclist (including the mass of his bike) to climb the famed 1100-m-high Alpe d'Huez mountain stage

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 =
