A) f
B) \[1.27f\]
C) \[\text{1}.0\text{1}\times \text{1}{{0}^{\text{5}}}\text{ N}/{{\text{m}}^{\text{2}}}\]
D) \[\text{9}.\text{13}\times \text{1}{{0}^{\text{4}}}\text{ N}/{{\text{m}}^{\text{2}}}\]
Correct Answer: B
Solution :
Source and observer both are moving, so apparent frequency \[\text{9}.\text{13}\times \text{1}{{0}^{\text{3}}}\text{N}/{{\text{m}}^{\text{2}}}\] \[\text{18}.\text{26 N}/{{\text{m}}^{\text{2}}}\] where, v = speed of sound \[\text{2}.\text{25}\times \text{1}{{0}^{\text{3}}}\text{min}\] \[\text{3}.\text{97}\times \text{1}{{0}^{\text{3}}}\text{min}\] \[9.13\times {{10}^{3}}N/{{m}^{2}}\]You need to login to perform this action.
