The equation of a travelling plane sound wave has the form `y=60 cos (1800t-5.3x)`, where y is in micrometres, t in seconds and x in metres. Find
(a). The ratio of the displacement amplitude with which the particle of the medium oscillate to the wavelength,
(b).the velocity oscillation ammplitude of particles of the medium and its ratio to the wave propagation velocity , (c ).the oscillation amplitude of relative deformation of the medium and its relation to the velocity oscillation amplitude of particles of the medium, (d). the particle acceleration amplitude.

Explanation

To solve the problem step by step, let's break it down into parts as per the question.

### Given:
The equation of the traveling sound wave is:
\[ y = 60 \cos(1800t - 5.3x) \]
Where:
- \( y \) is in micrometers (µm)
- \( t \) is in seconds (s)
