Do waves carry momentum also along with energy?

$A$ spherical source of power $4 W$ and frequency $800 Hz$ is emitting sound waves. The intensity of waves at a distance $200 m$ is

If the ratio of the amplitude of two waves is $4:3$,then the ratio of their maximum and minimum intensity is:

As a wave propagates,which of the following statements is correct?

$A$ musical instrument $P$ produces sound waves of frequency $n$ and amplitude $A$. Another musical instrument $Q$ produces sound waves of frequency $n/4$. The waves produced by $P$ and $Q$ have equal energies. The amplitude of waves produced by $Q$ will be

The intensity of sound after passing through a slab decreases by $30\%$. On passing through two such slabs,the intensity will decrease by ..... $\%$
