Answer:
1800 m/s
Explanation:
The equation is v = fλ
λ= 0.75
f = 2400 Hz
V = 2400 × 0.75
V = 1800 m/s
[ you did not give units for wavelength, I assumed it would be m/s]
The gravity is pushing rhe boat down
Explanation:
If the size and direction of the forces on the object are exactly balanced , then there is no net force acting on the object
