A circular loop of wire of radius R is perpendicular to a magnetic field whose magnitude as a function of time t is given by the equation , where b and c are positive, nonzero constants. What is the magnitude of the emf induced in the loop as a function of time t

As shown in fig. p3.64, a closed, rigid tank fitted with a fine-wire electric resistor is filled with refrigerant 22, initially at 2108c, a quality of 80%, and a volume of 0.01 m3. a 12-volt battery provides a 5-amp current to the resistor for 5 minutes. if the final temperature of the refrigerant is 408c, determine the heat transfer, in kj, from the refrigerant.
