Answer : The correct option is,

Particles Charge Location

Proton + inside nucleus

Electron - outside nucleus

Neutron 0 inside nucleus

Explanation :

As we know that an atom is the smallest unit of a matter that consist of three subatomic particles which are electrons, protons and neutrons.

The protons and the neutrons are located inside the nucleus or center of the nucleus where the mass of the an atom is concentrated and the electrons are located around the nucleus.

The protons are positively charged, the electrons are negatively charged and the neutrons are neutral that means it has no charge.

From the given table, we conclude that

The particle proton has positive charge and location is inside the nucleus.

The particle electron has negative charge and location is outside the nucleus.

The particle neutrons has no charge and location is inside the nucleus.

A mixed cost contains Select one:

-Dominant- [34]

A mixed cost contains a variable element and a fixed element.

Option a

<u>Explanation:</u>

Mixed costs are those costs that has both variable and fixed component. Example: operating cost of a machinery includes fixed costs that cannot be changed with other variable costs like fuel, insurance, depreciation, etc.

It is also named as semi-variable costs. And the formula to calculate mixed cost is as follows,

$y=a+b x$

where,

y is the "total cost "
a is the "fixed cost per period"
b is the "variable rate per unit of activity"
x is the "number of units of activity"

Usually, when the temperture is increased l, what will happen to the ratevof dissolving?

pochemuha

<span>When temperature is increased, the rate of dissolving increases. The kinetic energy of the molecules of the solute and solvent molecules is high thereby increasing their contact. An example is mixing powdered sugar to the water. When you add water to the sugar, the dissolving process is slow. However, when you increase the temperature of the water by boiling it, the sugar dissolves immediately. </span>
