The speed of sound at 0°C in open air is 331.3 m/sec. At what temperature would the wavelength of a 440 Hz sound wave be 0.82 meters?
Equation to find the speed of sound: Vт = Vo √(T/273)
T = 273 + t(°C)
My calculations:
Vт = 440 Hz (0.82 m) = 360.8 m/s
Vт = Vo √(T/273)
360.8 m/s = 331.3...

Comic-strip hero Superman meets an asteroid in outer space and hurls it at 800 m/s, as fast as a bullet. The asteroid is a thousand times more massive than Superman. In the strip, Superman is seen at rest after the throw. Taking physics into account, what would be his recoil...
