When boat is sunk into the liquid the net buoyancy on the boat is counterbalanced by weight of the boat
So here weight of the boat = Buoyancy force
let say boat is sunk by distance "h"
now we can say
now by above force balance equation we can write
so boat will sunk by total 5 mm distance
Answer:
wavelength = 5.50 m
The period T = 5.80 s
The speed v = 0.948 m/s
Amplitude A of each wave = 0.350 m
Explanation:
Since the wave crests is 5.50 m; then we can say that the distance from one peak to another is equal to a single wavelength;
SO; wavelength = 5.50 m
Given that ; the time to travel from the highest point to the lowest point = 2.90 s
Thus ; which implies just only about half of one wavelength
The period for one wavelength T = twice of half of one wavelength which can be expressed as :
T =
T = 2 (2.90 s)
T = 5.80 s
The speed of the wave can be determined via the formula;
The amplitude A is half the distance because the distance illustrates the peak to peak vertical displacement of the wave ;
∴
A =
A = 0.350 m
