173120 In case of a forced vibration, the resonance wave become very sharp when the:

1 quality factor is small
2 damping force is small
3 restoring force is small
4 applied periodic force is small

173130 If a resonance tube is immersed in water of density $\left(\rho_{w}\right)$ and then in liquid of density $\left(\rho_{L}\right)$ $\rho_{L}>\rho_{w}$, then its frequency in liquid will

1 increase
2 decrease
3 remain the same
4 depend on density of liquid

173132 A sound wave of frequency ' $v$ ' $\mathrm{Hz}$ initially travels a distance of $1 \mathrm{~km}$ in air. Then it gets reflected into a water reservoir of depth $600 \mathrm{~m}$. The frequency of the wave at the bottom of the reservoir is $\left(V_{\text {air }}=340 \mathrm{~m} / \mathrm{s} ; V_{\text {water }}=1484 \mathrm{~m} / \mathrm{s}\right)$

1 $>\mathrm{vHz}$
2 $
3 $v \mathrm{~Hz}$
4 0 (the sound wave gets attenuated by water completely)
