Question

Forces in Fluid
Let us assess
1.
The weight of a piece of stone in air is 120 N and its weight in
water is 100 N. Calculate the buoyancy experienced by the stone.
A body, which floated in water, sank when put in kerosene. Why
did it happen?
Observe the figures of an object placed in different liquids.

a.
Compare the gravitational force and the buoyancy acting on
the body when it is in the liquids A and B.
Among A and B, which is the liquid whose density is greater
than that of the object? Why?
b.​

Answer 1

Answer:

There are no results for 1. Find the tangent line to the curve y = vx at x = 4 (1) y=x 1 () v= 3x-2 (2) y = 3x -2 (3) y = 5x 7 (4) y = 4x 8

Answer 2

1)buoyancy=weight of stone in air-weight of stone in in water

120N-100N=20N

2) kerosene has lower density then water. so kerosene can not exert more buoyancy when compared with water.

3)(a) In the liquid A, buoyancy is greater than the gravitational force.ln B, buoyancy is less than the gravitational force,

(b) liquid A. as the body floats, the density of liquid is is greater.
