Consider the situation shown in figure. The frame is made of the same material and has a uniform 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` .

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 rod is made of uniform material and has non-uniform cross section. It is fixed at both the ends as shown and heated at mid-section. Which of the following are not correct?

Find the rate of heat flow through a cross section of the rod shown in figure (theta_(2)gttheta_(1) . Thermal conductivity of the material of the rod is K.

The ratio of cross-sectional areas of two conducting wires made up of same material and having same length is 1: 2. What will be the ratio of heat produced per second in the wires, when same current is flowing in them?

Two rods (one semi-circular and other straight) of same material and of same cross-sectional area are joined as shown in the figure. The point A and B are maintained at different temperature. Find the ratio of the heat transferred through a cross-section of a semi-circular rod to the heat transferred through a cross section of the straight rod in a given time.

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 formss a diameter of the other rod. The junction are maintaine dat different temperature. Find the ratio of the heat transffered through a cross section of the straigh rod in a given time.

An irregular rod of same uniform material as shown in is conducting heat at a steady rate. The temperature gradient at varoius sections versus area of cross section graph will be .
