Physics Elasticity Question 26
Question: The pressure of a medium is changed from 1.01 ยด 105 Pa to 1.165 ยด 105 Pa and change in volume is 10% keeping temperature constant. The Bulk modulus of the medium is
Options:
A) $ 204.8\times 10^{5}Pa $
B) $ 102.4\times 10^{5}Pa $
C) 51.2 ยด 105Pa
D) 1.55ยด 105 Pa
Show Answer
Answer:
Correct Answer: D
Solution:
$ K=\frac{\Delta p}{\Delta V/V} $
$ =\frac{(1.165-1.01)\times 10^{5}}{10/100}=\frac{0.155\times 10^{5}}{1/10} $
$ =1.55\times 10^{5}pa $
