A) \[{{(T-T)}^{4}}\]
B) \[{{T}^{4}}-{{t}^{4}}\]
C) \[{{(T-t)}^{1/4}}\]
D) \[{{T}^{2}}-{{t}^{2}}\]
Correct Answer: B
Solution :
[b] According to Stefan' law heat emitted per second per unit area a\[\alpha (T{}_{1}^{4}-T{}_{2}^{4})\] where \[{{T}_{1}}\] is the temperature of body & \[{{T}_{2}}\] is the temperature of surrounding (\[{{T}_{1}}\] & \[{{T}_{2}}\] are on Kelvin scale).You need to login to perform this action.
