The speed of sound in air is dependent on temperature and seems to follow the equation v = 331 + 0.6 Tc Where v is measured in m/s and Tc is the temperature measured in Celsius. (a) What is the speed of sound on a cold day when Tc = 4°C (b) What is the speed of sound at room temperature when Tc = 20°C (c) What is the speed of sound on a warm day when Tc = 38°C (2) In attempting to tune a string musical instrument to match the oboe's A = 440 Hz, a beat frequency of 2 Hz is noted. What are the two possible frequencies of the string instrument?

The speed of sound in air is temperature dependent. This theoretical value can be calculated using v = 331 m s + 0.6T where T is the temperature of the air in degrees Celsius. If you can measure the air temperature, calculate the actual speed of sound. Otherwise, use 343 m s which is based on 20 ° C . 2 . Calculate the percent error between your experimental value for the speed of sound in air and the actual value of 343 m s . Record your percent error in the box below. % Error = | Actual - Experimental | Actual × 100 % What caused the error in your experimental value for the speed of sound in air, and what could you have done differently to improve the results of this activity?

What is the temperature of the air if the speed of sound is measured as 330 m/s (use the Celsius temperature calculation: v = 331 + 0.6T) ? (include units with answer)
