A rod of negligible heat capacity has a length of 50 cm, area of cross section `5cm^(2)` and thermal conductivity 500 `W//m^(@)C`. The temperature of one end is maintained at `0^(@)C` and that fo the other end is slowly and linearly varied from `0^(@)C` to `60^(@)C` in 20 min. Assuming no heat loss through the lateral side, the total heat transmitted throught he rod in 20 minutes is

A rod of negligible heat capacity has length 20cm, area of cross section 1.0cm^(2) and thermal conductivity 200Wm^(-1)C^(-1) . The temperature of one end is maintained at 0^(@)C and that of the other end is slowly and linearly varied from 0^(@)C to 60^(@)C in 10 minutes. Assuming no loss of heat through the sides, find the total heat transmitted through the rod in these 10 minutes.
