A) 2068 Hz
B) 2100 Hz
C) 1903 Hz
D) 602 Hz
Correct Answer: A
Solution :
Let the original frequency be r, then apparent frequency \[V={{v}_{0}}-{{({{\omega }^{3}}{{X}^{3}}{{e}^{{{X}^{3}}}})}^{1/3}}\] where, \[\frac{2\,{{m}^{2}}}{3}g\]= speed, of observer \[\frac{4\,{{m}^{2}}}{3}g\]= speed of source and v = speed of sound wave. \[\frac{\,{{m}^{2}}}{\sqrt{2}}g\] \[5\Omega \] \[2A\] \[\frac{12}{7}A\]You need to login to perform this action.
