The frequency (f) in hertz (1/s) of the sound waves is the quotient when its speed (S) is divided by the wavelength (n). This is mathematically expressed,
f = S / n ; f = (331 m/s) / (0.6 m) = 551.67 / s
Thus, the frequency of the wave is 551.67 Hz.
Answer:
24 kgm/s
Explanation:
Momentum (p) = mass x velocity
Mass = 3kg , velocity 8m/s
momentum (p) = 3kg x 8m/s
= 24kgm/s
The combination of all of the forces acting on object is net force.
