a rod of uniform cross sectional area A, length l and thermal conductivity k has negligible heat capacity. the one end of the rod is maintained at temperature 100 degree celsius and the temperature of the other end varies with time according to T=t^2/100 where T is temperature and t is time. the total heat transferred through the rod in t=0 to t=5 sec is

For a small time dt The heat transferred is dQ/dt= (KA*dT)/L dT is 100- t^2/100 dQ= KA(100-t^2/100) /L *dt integrate t from 0 to 5 to find Q
