A) 108 joules approx.
B) 168 joules approx.
C) 182 joules approx.
D) 192 joules approx.
Correct Answer: C
Solution :
Rate of heat loss \[E=\sigma \,eA({{T}^{4}}-T_{0}^{4})\] \[=5.67\times {{10}^{-8}}\times 0.4\times 200\times {{10}^{-4}}\]\[\times \]\[[{{(273+527)}^{4}}-{{(273+27)}^{4}}]\] \[=5.67\times {{10}^{-8}}\times 0.4\times 200\times {{10}^{-4}}\]´\[{{(800)}^{4}}-{{(300)}^{4}}\] =182J/secYou need to login to perform this action.
