A and B are two sphere made of same material. Radius of A is double that of B and initially they are at same temperature (T). Both of them are kept far apart in a room at temperature `T_(0)(lt T)`. Calculate the ratio of initial rate of cooling (i.e. rate of fall of temperature) of sphere A and B if
(a) the spheres are solid,
(b) the spheres are hollow made of thin sheets of same thickness

There are two thin spheres A and B of the same material and same thickness. They behave like black bodies, Radius of A is double that of B and Both have same temperature T. When A and B are kept in a room of temperature T_0 (lt T) , the ratio of their rates of cooling is (assume negligible heat exchange between A and B).

A cube and a sphere (both solid) of same mass, same material are heated upto same temperature and then kept in same surrounding. Rate of cooling means rate of fall of temperature

A solid cube and a sphere are made of the same material and both have the same surface area. If both are at the temperature of 300 K then initial
