Answer:
Wavelength of wave is 2.5 meters
Explanation:
Given that,
Speed of a wave, v = 350 m/s
Frequency of the wave, f = 140 Hz
The formula to find the speed of sound is given by :
The speed of sound is more in higher temperature. At higher temperature, the molecules vibrate with more energy. As a result, sound travel faster in a warm room.
Answer:
Decreasing the use of fossil fuels will improve the wellbeing of animals (and people, for that matter).
