Conside the situation shown in figure. The frame is made of the same material and has a unifrom cross-section area everywhere. Calculate the amount of heat flowing per second through a cross section of the bent part if the total heat taken out per second from the end at `100^(@)C` is `130J` .

Consider the situation shown in figure. The frame is made of the same material and has a uniform cross-sectional area everwhere. If amount of heat flowing per second through a cross-section of part A is 60J . The amount of total heat taken out per second from the end at 50^(@)C is 0.132 xx 10^(n) J//s . Find 'n'.

A semicircular rods is joined at its end to a straight rod of the same material and the same cross-sectional area. The straight rod forms a diameter of the other rod. The junctions are maintained at different temperatures. Find the ratio of the heat transferred through a cross section of the straight rod in a given time.
