Answer:2200 hz
Explanation:
speed=242m/s
Distance between crest is there wavelength=0.11m
Frequency=speed ➗ wavelength
Frequency=242 ➗ 0.11
Frequency=2200
Frequency=2200 hz

Answer:
372,400 N
Explanation:
The volume of the column is ...
V = Bh = (2 m^2)(19 m) = 38 m^3
If we assume the density is 1000 kg/m^3, then the mass of the water is ...
M = ρV = (1000 kg/m^3)(38 m^3) = 38,000 kg
The force of gravity on that mass is ...
F = Mg = (38,000 kg)(9.8 m/s^2) = 372,400 N
