A wire loop with a radius of 8.5 cm is initially parallel to a uniform magnetic field 3.6 T. The loop's orientation is then changed so that it is perpendicular to the field in 0.15 s. What is the induced emf in the loop

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 =
