1.	A large tank of water at a constant temperature of 90^(0)C is connected to a small vessel containing 10kg water at 10^(0)C, through a metal rod of length 2m, area of cross-section 0.5m^(2) and thermal conductivity of 20 units. If the time taken for the temperature of the water in small vessel at 30^(0)C is t=Nxx4200log(4//3), then find the value of N. (Given, specific heat of water =4200" J kg"^(-1)""^(0)C^(-1))
