If a black body at 400 K surrounded by atmosphere at 300 K has rate of cooling \( \propto T^4 \), the same body at 900 K, surrounded by same atmosphere, will have rate of cooling nearly

Two spherical black bodies have radii $R_{1}$ and $R_{2}$ and temperatures $T_{1}$ and $T_{2}$. If they radiate same power, then $R_2/R_1$ is}

Two stars 'A' and 'B' radiate maximum energy at \(5200\text{ \AA}\) and \(6500\text{ \AA}\) respectively. Then the ratio of absolute temperatures of stars ' A ' and ' B ' is
