Answer 1

Given ,

Potential difference (v) = 300

Capacitance (C) = 20 PF

We know that ,

The charge required to increase the potential difference of the conductor unit amount is called capacitance

$\large \mathtt{ \fbox{Capacitance \: (C) = \frac{q}{v} }}$

Thus ,

20 = q/300

q = 20 × 300

q = 6000 Pc

Hence , the charge is 6000 Pc

Answer 2

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.
