Two large parallel conducting plates separated by 13 cm carry equal and opposite surface charge densities such that the electric field between them is uniform. The difference in potential between the plates is 300 V. An electron is released from rest at the negatively charged plate. (a) What is the magnitude of the electric field between the plates

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 =
