Answer:
1.)799.65mph
2.)739.59mph
3.)INCREASES-When the temperature increases the speed of sound also increase because particles move faster in higher temperature.
DECREASES-At a lower temperature, particles of the medium are moving more slowly, so it takes them longer to transfer the energy of the sound waves. ... A: For each 1 degree Celsius that temperature decreases, the speed of sound decreases by 0.6 m/s. So sound travels through dry, -20 °C air at a speed of 319 m/s.
4.)Temperature is another condition that affects the speed of sound. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy and can vibrate faster and allow sound waves to travel more quickly. ... The speed of sound is also affected by other factors such as humidity and air pressure.
