The rectangular surface of area 8 cm xx 4 cm of a black body at temperature 127^(@)C emits energy E per section if length and breadth are reduced to half of the initial value and the temperature is raised to 327^(@)C , the ratio of emission of energy becomes

The rectangular surface of area 8 cm xx 4 cm of a black body at temperature 127^(@)C emits energy E per section if length and breadth are reduced to half of the initial value and the temperature is raised to 327^(@)C , the ratio of emission of energy becomes

The rectangular surface of area 8cmxx4cm of a black body at a temperature of 127^(@)C emits energy at rate of E per second. If the length and breadth are reduced to half of its initial value and the temperature is raised to 327^(@)C , the rate of emission of energy will be

The rectangular surface area 12cm xx 6cm of a black body at a temperature of 127^(@)C , emits heat energy at the rate of Q units per second. If the length and breadth of the surface area are each reduced to half of its initial value and the temperature is increased to 327^(@)C , then the rate of emission of heat energy will be
