Question

A boat floating in water has a mass of 1000kg. If the upthrust is floated in denser salt water , what effect does it have on
1) the upthrust
2)the weight of the water displaced
3)the level at which the boat floats?

Answer 1

1) The upthrust would increase in denser salt water compared to regular water because the density of the salt water is higher, resulting in a greater buoyant force.

2) The weight of the water displaced would also increase in denser salt water because the upthrust is greater, necessitating more water to be displaced in order to counteract the boat's weight.

3) The level at which the boat floats would likely be lower in denser salt water compared to regular water because the increased upthrust would lift the boat higher out of the water.
