Group Title
Pressure variation of helium gas in equilibrium is given by \[\triangle P=2.9x{ 10 }^{ 5 }cos(6.2x3000t)\] where x and t have units m and s.
What is the speed of the wave?
This is a practice problem, I have the answer but no method on doing it. Honestly, have no idea how to start thinking about this.
Any help?
