A thin rod of length 0.88 m rests on a fulcrum at its midpoint. A mass of 0.23 kg is placed at one end of the rod. Where must a mass of 0.43 kg be placed to balance
the rod (a = 0 rad/s)?

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 =
