Understanding Sound Waves and Their Speed

How does the speed of sound in air change with temperature?

• It increases as the temperature increases.

• It decreases as the temperature decreases.

• It decreases as the temperature increases.

• It remains constant regardless of temperature.

What is the formula used to calculate the speed of sound in air based on temperature?

• V = 331 - 0.59 * temperature in degrees C

• V = 331 / 0.59 * temperature in degrees C

• V = 331 + 0.59 * temperature in degrees C

• V = 331 * 0.59 + temperature in degrees C

In the given problem, what is the initial step to find out how far the mountain is?

• Measure the temperature of the air.

• Use the kinematics equation to find the distance.

• Calculate the time taken for the sound to travel.

• Estimate the speed of sound without calculations.

What is the calculated speed of sound at 4°C in the problem?

• 335 m/s

• 333 m/s

• 329 m/s

• 331 m/s

Why is the total distance calculated divided by two in the problem?

• To account for the sound traveling in a straight line.

• To adjust for the speed of sound in different temperatures.

• To correct an error in the initial calculation.

• Because the initial calculation includes the round trip to the mountain and back.
