Question

the speed of sound in air at 0°c is 331 m/s find the increase in the speed of sound as the temperature changes from -10°c to 37°c​

Answer 1

Explanation:

Speed= 339m/s

Speed= 339m/s Wavelength=3cm

Speed= 339m/s Wavelength=3cmnow change it to meter

Speed= 339m/s Wavelength=3cmnow change it to meterA=3/100

Speed= 339m/s Wavelength=3cmnow change it to meterA=3/100=0.03m

Speed= 339m/s Wavelength=3cmnow change it to meterA=3/100=0.03mspee=wavelength×frequency

Speed= 339m/s Wavelength=3cmnow change it to meterA=3/100=0.03mspee=wavelength×frequency=339m/s=0.03×frequency

Speed= 339m/s Wavelength=3cmnow change it to meterA=3/100=0.03mspee=wavelength×frequency=339m/s=0.03×frequency frequency=

Speed= 339m/s Wavelength=3cmnow change it to meterA=3/100=0.03mspee=wavelength×frequency=339m/s=0.03×frequency frequency= 0.03m

Speed= 339m/s Wavelength=3cmnow change it to meterA=3/100=0.03mspee=wavelength×frequency=339m/s=0.03×frequency frequency= 0.03m339m/s

Speed= 339m/s Wavelength=3cmnow change it to meterA=3/100=0.03mspee=wavelength×frequency=339m/s=0.03×frequency frequency= 0.03m339m/s

Speed= 339m/s Wavelength=3cmnow change it to meterA=3/100=0.03mspee=wavelength×frequency=339m/s=0.03×frequency frequency= 0.03m339m/s

Speed= 339m/s Wavelength=3cmnow change it to meterA=3/100=0.03mspee=wavelength×frequency=339m/s=0.03×frequency frequency= 0.03m339m/s =11300Hz

Speed= 339m/s Wavelength=3cmnow change it to meterA=3/100=0.03mspee=wavelength×frequency=339m/s=0.03×frequency frequency= 0.03m339m/s =11300HzIt is more than 11300Hz. Therefore, it will not be audible to the human ear.

Answer 2

Explanation:

the speed of sound in air at 0°c is 331 m/s find the increase in the speed of sound as the temperature changes from -10°c to 37°c
