Answer:
The wavelength of the water is
Explanation:
From the question awe are told that
The distance between the two boats are 46 m
Now we are told that a the time the Jenny's boat is at a crest,Melissa's boat is at its lowest point, and there are 4 additional crests between them which can be mathematically represented as
Number of wavelength = 4 + 0.5(this accounts for the difference in position crest and lowest point)
= 4.5
Now the wavelength of the water is
Answer:
1. Lead
2. Aluminum
3. Wood
4. Styrofoam
Explanation:
Specific gravity is a quantity that tells me how much an object is submerged on a fluid relating the densities:
Because all the cubes are placed on water, the density of the fluid is the same for all the cubes and S.G. is directly proportional to the density of the cube material. So, for greater density greater S.G.
The Archimedes principle states that the buoyant force is equal to the weight of water displaced, that is:
So, the cube that submerges more is the cube that mor displace water and is the cube that has more buoyant force on it. In other words, the cubes with higher S.G. have more buoyant force, and because S.G is proportional to cube density, the cubes with more buoyant force have more density.
