A) \[15{}^\circ C\]
B) \[12{}^\circ C\]
C) \[4{}^\circ C\]
D) \[11{}^\circ C\]
Correct Answer: C
Solution :
[c] Speed of wave from wave equation |
\[\text{v=-}\frac{\text{(coeffecient}\,\text{of}\,\text{t)}}{\text{(coeffecient}\,\text{of}\,\text{x)}}\] |
\[\text{v=-}\frac{1000}{(-3)}=\frac{1000}{3}\] |
since speed of wave\[\propto \sqrt{T}\] |
so\[=\frac{1000}{\frac{3}{336}}=\sqrt{\frac{273}{T}}\]\[\Rightarrow T=277.41K\] |
\[T=4.41{}^\circ C\] |
Option (c) |
