A) \[18{}^\circ C\]
B) \[20{}^\circ C\]
C) \[22{}^\circ C\]
D) \[25{}^\circ C\]
Correct Answer: C
Solution :
[c] \[\Delta t=\frac{1}{2}\alpha \Delta T\times t\] \[\therefore 5=\frac{1}{2}\alpha \left( T-15 \right)\times 86400\] and \[10=\frac{1}{2}\alpha \left( 30-T \right)\times 86400\]You need to login to perform this action.
