or p=m' x v
since in physics p is quantity momentum and m stands for mass and v stands for velocity.
Hope this helps :)
It's very hard to see the self-portrait, so I can't identify him.
Answer:
The frequency of the sound wave is 800Hz
The speed of sound in a is about 340m/s.
Velocity = frequency x wavelength
making wavelength the subject formula
wavelength = Velocity/frequency.
wavelength = 340/800
wavelength = 0.425m.
Answer:
They would land at the same time
Explanation:
They would land at the same exact time.
