A) (1/7) m
B) (1/8) m
C) (1/9) m
D) (1/10) m
Correct Answer: C
Solution :
[c] \[{{Q}_{1}}=kA\left( \frac{800-100}{x} \right)t=m{{L}_{stream}}\] \[{{Q}_{2}}=kA\left( \frac{800-100}{1-x} \right)t=m{{L}_{ice}}\] Dividing \[\left( \frac{700}{x} \right)\left( \frac{1-x}{800} \right)=7\] or \[1-x=8x\,\,or\,\,x=\frac{1}{9}m\]You need to login to perform this action.
