At t = 0, a battery is connected to a series arrangement of a resistor and an inductor. at what multiple of the inductive time constant will the energy stored in the inductor's magnetic field be 0.565 its steady-state value?

What is the role of lenses in microscopy?

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 =
