A) \[{{M}_{1}}\]
B) \[{{Z}_{2}}\]
C) \[{{M}_{2,}}\]
D) \[{{r}_{0.}}\]
Correct Answer: D
Solution :
For a rod of length L and area of cross-section A whose faces are maintained at temperature \[{{E}_{y}}=2.5\frac{N}{C}\cos \left[ \left( 2\pi \times {{10}^{6}}\frac{rad}{m} \right)t \right.\] and \[\left. -\left( \pi \times {{10}^{-2}}\frac{rad}{s} \right)x \right]\] respectively. Then in steady state the rate of heat flowing from one face to the other face in time t is given by\[{{E}_{s}}=0.\] The curved surface of rod is kept insulated from surrounding to avoid leakage of heat.You need to login to perform this action.
