Differential Equations

Have you ever observed the movement of the satellites and rockets or how the planets go around the sun in their orbits? How will you determine their motion? Definitely they follow some scientific laws and these kinds of problems are framed as differential equations.

Question

Example: In a reverberation room whose volume is 150 m3 and
surface area is 190 m?, the reverberation time at 500 Hz is 6.9 s
when empty. When a specimen wall of 12 m? area is installed in
the room, the reverberation time is 3.4 s. Find the absorption
coefficient of the wall at 500 Hz.
