Question

the side of a square is measured to be 12.4cm+_0.1cm.find the error in a calculation of its perimeter​

Answer 1

Given ,

Side of a square = 12.4 ± 0.1 cm

We know that , the perimeter of square is given by

$\large \mathtt{ \fbox{Perimeter= 4 × Side }}$

$\therefore$ the error in perimeter of square is

$\large \mathtt{\fbox{ \frac{Δ \: Perimeter}{Perimeter } = \frac{Δ \: Side}{Side} }}$

Thus ,

$\sf \hookrightarrow \frac{Δ \: Perimeter}{Perimeter } = \frac{0.1}{12.4} \\ \\ \sf \hookrightarrow \frac{Δ \: Perimeter}{Perimeter } = 0.0080$

Hence , the error in perimeter of square is 0.0080

Answer:

CHEMISTRY

A solution is defined as a:

A .

Homogeneous mixture of two or more substances

B .

Heterogeneous mixture of two or more substances

C .

Homogeneous mixture of liquid and solid components only

D .

Homogeneous mixture consisting of water as one of the components

A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase. 

A solution consists of a solute and a solvent. 

The solute is the substance that is dissolved in the solvent.

For example, in a saline solution, salt is the solute dissolved in water as the solvent.
