Question

Consider a large ship in the Cape Fear River moving toward the ocean. As the ship moves from fresh water into saltwater, it should rise sink a small amount due to the change in water density. Circle one choice and explain your answer. Atmospheric pressure near the earth surface is about 15 pounds per square inch, meaning that we always being squeezed inward by 15 pounds of force per square inch. What do you think would happen to a human body if this pressure were to disappear, such as in outer space (which is a vacuum of nearly zero pressure)? Imagine that you are treading water in the Meredith swimming pool. What is the weight of water (in Newtons) that a 80 kg person must displace (push aside) in order for them to float? A cubic meter is easy to visualize if you consider a gallon container of milk. What is the volume of water they must displace in cubic meters? 1 cubic meter of water weighs 9.8 times 10^4 N. Explain your answer. Weight of water that must be displaced in order to float = N Volume of water that must be displaced in order to float = m^3

Explanation / Answer

When a ship floats on water, it floats due to the bouyancy created by the water displaced by the ship. The weight of the displaced water is equal to the weight of the boat.

Now since the density of sea water i.e. salt water is higher than the density of plain water so it can displace the same weight of water with lesser volume. therefore, the ship on entering from river to sea water will rise a little bit.
