Question

The correct relation is:- *
1 point
a) R.D. =density of water / density of the substance
b) R.D. = Density of Substance x density of water
c) R.D. = density of the substance / density of the water​

Answer 1

c no lls make me as a brainlost

Answer 2

Solution:

The correct relation is R.D = Density of substance / Density of the water.

Know more:

$\begin{gathered}\boxed{\begin{array}{c}\\ {\pmb{\sf{Some \: formulas!}}} \\ \\ \sf \star \: Density \: = \dfrac{Mass}{Volume} \\ \\ \sf \star \: Volume \: = \dfrac{Mass}{Density} \\ \\ \sf \star \: Density \times Volume = Mass \end{array}}\end{gathered}$

• Density: Density is defined as the mass of a unit volume of the given substance. It's SI unit is kilogram per metre cube.

• Density of water is 1000 kg/m³.

• Relative density have no SI unit.

➟ The force acting on an object perpendicular to the surface is known as thrust.

➟ The thrust on unit area is known as pressure. Henceforth,

• ${\small{\underline{\boxed{\sf{Pressure \: = \dfrac{Thrust}{Area}}}}}}$

It can be also written as

• ${\small{\underline{\boxed{\sf{Pressure \: = \dfrac{Force}{Area}}}}}}$

➟ SI unit of pressure is N/m² but in honour of scientist Blaise Pascal it's SI is Pascal that is denoted by Pa.
