1.	If the temperature of the Sun were to increase from T to 2T and its radius from R to 2R. The ratio of radiant energy received on earth to what it was previously will be. . . .. . .
Answer» 4 16 32 64 Solution :The AMOUNT of radiant ENERGY, `W=esigmaAT^(4)` (Stefan-Boltzmann.s law) `W=e SIGMA(4piR^(2))T^(4)(becauseA=4piR^(2))` `WpropR^(2)T^(4)` `:.(W_(2))/(W_(1))=((R_(2))/(R_(1)))^(2)((T_(2))/(T_(1)))^(4)` `=((2R)/(R))^(2)((2T)/(T))^(4)` `=4xx16=64`
