Question

5) A 5 kg iron ball sinks in water whereas a 5 kg iron ship floats on water because *

1. the shape of the ship is such that it allows it to float.
2. the ship is shaped so as to displace more water.
3.the weight of the ship is same as the weight of the water displaced by it.
4. all of the above

Answer 1

Answer:

Here is the answer . I did not understand the question , so next time try to

post a question which will be comfortable to read and understand.

Explanation:

1. If the boat weighs less than the maximum volume of water it could ever push aside (displace), it floats. But it sinks into the water until its weight and the upthrust exactly balance
2. Its shape causes the ship to displace much more water than the ball. In fact, the weight of the displaced water is greater than the weight of the ship. As a result, the buoyant force is greater than the force of gravity acting on the ship, so the ship floats.
3. A body immersed in fluid is subject to an upwards force equal to the weight of the fluid displaced. The displacement of a ship, D, is defined as the number of tones of water it displaces.
