An electric toaster works by radiative heat transfer. On each side of a four-slice toaster, there are eight ribbons of wire 0.50 m long, and rectangular in cross-section 1/8 cm wide by 1/20 cm thick. When operating, the toaster consumes a certain amount of power. Assuming all that power goes into heating the toaster wire, and emissivity = 1 for the wire, find the working temperature of the wires, in °C. %3D

2. A bank of nickel-cadmium cells is used as the emergency lighting supply for a hospital. There are 100 cells connected in series and each has an A-hr rating of 120 A-hr. The bank has to be replaced, and the manufacturer is no longer supplying nickel-cadmium cells. It is decided to replace the cells with lead-acid cells. How many lead-acid cells will be required if each has an A-hr rating of 60 A-hr, and how should they be connected?
