A satellite is spinning at 6.2 rev/s. The satellite consists of a main body in the shape of a solid sphere of radius 2.0 m and mass 10,000 kg and two antennas projecting out from the center of mass of the main body that can be approximated with rods of length 3.0 m each and mass 16 kg. The antennas lie in the plane of rotation. What is the angular momentum of the satellite about its center?

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 =
