Final answer:
The speed of sound in air at 56.0°C is approximately 364.6 m/s. However, since this value is not offered in the multiple-choice options, the closest available option, which is 362 m/s, should be selected.
The Correct otion is; d) 362 m/s
Step-by-step explanation:
To calculate the speed of sound in air at a given temperature, you can use the formula:
Speed of sound in air (v) = 331 m/s + (0.6 × Temperature in °C)
At a temperature of 56.0°C, the calculation would be:
Speed of sound = 331 m/s + (0.6 × 56.0°C)
Speed of sound = 331 m/s + 33.6 m/s
Speed of sound = 364.6 m/s
However, this value is not amongst the options provided. The closest option to the calculated speed of sound is 362 m/s(d).
It is important to note that while 364.6 m/s is the calculated value, the actual speed of sound can vary slightly due to factors such as humidity and air pressure.
Nonetheless, the question provides discrete options, so the one that is closest to the calculated value should be chosen.
