354728 A source \(S\) and an observer \(O\), moving with speeds \(v_{1}\) and \(v_{2}\) respectively, are moving away from each other. When they are separated by distance \(a(t=0)\), a pulse is emitted by the source. This pulse is received by \(O\) at time \({{\text{t}}_1}\) then \(t_{1}\), is equal to (velocity of sound is \(v_{s}\) )
354729 A person observes two moving trains, ' \(A\) ' reaching the station and ' \(B\) ' leaving the station with equal speed of \(30\;m/s\). If both trains emit sounds with frequency \(300\;Hz\), (Speed of sound: \(330\;m/s\)) approximate difference of frequencies heard by the person will be:

In the given arrangement a source is placed at the fixed end of the spring with spring constant \(100\;N/m\) and the receiver is attached to the moving end of the spring, which is connected to a box of mass \(4\;kg\), which is oscillating horizontally with an amplitude of oscillation \(2\;m\). If the source emits a frequency of \(990\;Hz\) then (speed of sound \( = 330\;m/s\))
