Q. The velocity of a longitudinal sound wave in an ideal gas is given by where γ is the ratio of the specific heat at constant pressure to that at constant volume, P is pressure, and ρ is the mass density. Assume an ideal gas with and at standard temperature and pressure, find the wavelength for a sound wave.

Q. Boat A negotiates a curve whose radius is 363m. Boat B negotiates a curve whose radius is 110m. Each boat experiences the similar centripetal acceleration. What is the ratio of speed of boat A to that of boat B?
