can i get help with all parts, thanks

An acoustic sensor based instrument is to be designed for measuring the air temperature in a
steady environment by measuring the speed of sound in air. It is known that the speed of
sound in air, c (m/s), and the air temperature, T (°C), have the following relationship,
C = = k√T + 273.15 (T> 0 °C)
where k is a constant.
(a) Draw a block diagram to show the essential elements in the instrument.
(b)
With the aid of suitable equation(s), explain the principle of measuring the air
temperature using the acoustic sensing technique.
