In an experiment, a rectangular block with height h is allowed to float in two separate liquids. In the first liquid, which is w
Amiraneli [1.4K]

Answer:

The relative density of the second liquid is 7.

Explanation:

From archimede's principle we know that the force that a liquid exerts on a object equals to the weight of the liquid that the object displaces.

Let us assume that the volume of the object is 'V'

Thus for the liquid in which the block is completely submerged

The buoyant force should be equal to weight of liquid

Mathematically

F_{buoyant}=Weight\\\\\rho _{1}\times V\times g=m\times g\\\\\therefore \rho _{1}=\frac{m}{V}...............(i)

Thus for the liquid in which the block is 1/7 submerged

The buoyant force should be equal to weight of liquid

Mathematically

F'_{buoyant}=Weight\\\\\rho _{2}\times \frac{V}{7}\times g=m\times g\\\\\therefore \rho _{2}=\frac{7m}{V}.................(ii)

Comparing equation 'i' and 'ii' we see that

\rho_{2}=7\times \rho _{1}

Since the first liquid is water thus \rho _{1}=1gm/cm^3

Thus the relative density of the second liquid is 7.

develop an equation with a proportionality constant that describes the relationship between the gravitational force the mass of
Ganezh [65]
Let the mass of planet and moon be Mp and Mn respectively.
And the distance between them is "r"

Then according to Newton's law of gravitation,

The force with which the planet and the moon attract esch other is
1) directly proportional to the product of their masses i.e. Mp * Mn

2) inversly proportional to the square of the distance between them i.e r ^2

Therefore,F =. G (Mp* Mn)/r^2
Where,G is gravitational constant
