The speed of sound in air is dependent upon the air temperature and other factors.The speed of sound increases from 334 m/s to 341 m/s between 8:00am and 11:00am.If a horn produces sound with wavelength 0.75 m at 8:00am,what would it produce at 11:00am?
A) 73 cm
B) 77 cm
C) Not enough info given to solve.
D) 75 cm

The speed of sound is given by the formula v = fλ, where v is the speed, f is the frequency, and λ is the wavelength. The frequency remains constant, so the wavelength at 11:00am can be calculated using the ratio of speeds: (341/334) * 0.75 m = 0.767 m, which is approximately 77 cm.
