Two identical spools of ribbon are held the same height above the floor. the ribbon from spool a is tied to a support, while spool b is not connected to the support. both spools are released from rest at the same instant. assume that the mass of the ribbon is negligible compared to the mass of the spool. which spool hits the ground first? and at what horizontal position does spool a hit the ground, with respect to the position it is dropped from?

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 = 1Γ105 wm-2k-1 and tβ = 8000 k. when the nanowire grows to l = 300 nm, what is the temperature of the nanowire tip (t (x =
