If a the stream velocity is going at 200 cm/s, which particles can the stream move? Mention all possible particles.

Things that let electricity go through them are called

Anika [276]

Answer: they are called electrical conductors.

Explanation:

Some materials let electricity pass through them easily. These materials are known as electrical conductors. Many metals, such as copper, iron and steel, are good electrical conductors. That is why the parts of electrical objects that need to let electricity pass through are always made of metal.

Commercially available solution of SPT has a density of 3.10 g/mL. Water (1.00 g/mL) can be added to the original SPT solution,

Pepsi [2]

The reciprocal of the density, ρ, of a mixture is equal to the sum of the reciprocal of the densities of the constituents multiplied by their respective proportions ( $x_i$ ) in the solution, $\displaystyle \dfrac{1}{\rho_{(mixture)}} = \sum \dfrac{x_i}{\rho _i}$

The percentage of water in the 2.75 g/mL SPT solution is $\underline{16. \bar6 \ \%}$

Reason:

Known parameter:

Density of SPT = 3.10 g/mL

Density of water = 1.00 g/mL

Required:

The percentage of water in 2.75 g/mL SPT solution

Solution:

Let <em>x</em> the volume of water added per 100 mL of 2.75 g/mL SPT solution, we have;

Mass of water in the solution = x mL × 1.00 g/mL = x g

Mass of commercial SPT = (100 - x) mL × 3.10 g/mL = (310 - 3.1·x) g

$Density = \dfrac{Mass}{Volume}$

The density of the 2.75 g/mL SPT solution is given as follows;

$Density \ of \ 100\ mL, \ 2.75 \ g/mL = \dfrac{(310 - 3.1\cdot x + x) \ g}{100 \ mL}$

100 mL × 2.75 g/mL =( 310 - 2.1·x) g

310 - 275 = 2.1·x

$x = \dfrac{310 - 275}{2.1} = \dfrac{50}{3} = 16.\overline 6$

Given that the reference quantity of the proportion of water in the solution is 100 mL of the 2.75 g/mL SPT solution, the percentage (per 100) of water in the overall solution is the value of <em>x</em>

Therefore;

The percent of the SPT solution that must consist of water to give an overall density of 2.75 g/mL is x = $\displaystyle {\underline {16.\overline 6 \ \%} }$
