Question

2.A boat is floating on water

a) What is the force preventing the boat from sinking?

b)What are the factors that influence this force?​

Answer 1

a) buoyant force

b) factors : the density of fluid

the mass of immersed object

Answer 2

Answer:

(a) Upthrust (Buoyant force)

(b) Check the explanation

Explanation:

(a) Fact to remember

(b) Upthrust is given by=volume of the submerged part of the body* density of the fluid * the acc sue to gravity(g)

therefore we can easily say that Upthrust depend on the following factors:

(1)Volume of the submerged part of the body

(2) Density of the liquid in which the body is submerged

(3) Acceleration due to gravity at that specific place(g)

the Upthrust is directly proportional to all the above mentioned physical quantities,

NOTE: Upthrust does not depend on Mass of the body
