Explanation:

A cabbage juice is purple in color at pH = 7, which is also known as neutral pH.

And, cabbage juice will turn pink in color when an acidic medium is added to it. Therefore, when cabbage juice turns pink in soda then it means an acidic substance has been added to it.

On the other hand, cabbage juice will turn green in color when a basic medium is added to it. Therefore, when cabbage juice is green in the soapy water then it means soapy water is the basic medium.

Thus, we can conclude that soapy water is the basic substance.

All bases have a pH above 7, so the solution that turned green (the soapy water) is basic.

Consider the electric force between a pair of charged particles a certain
Crazy boy [7]

Answer:

Doubled

Explanation:

F = (kq1q2) / r^2

F and q (Either q1 or q2) are directly proportional, so double the charge would also double the electruc force between the charges.

A circuit contains four capacitors in parallel (10 F, 3 F, 7 F, and 1 F). What is the equivalent capacitance of this circuit?
Oxana [17]

The equivalent capacitance (C_{eq}) of an electrical circuit containing four capacitors which are connected in parallel is equal to: A. 21 F.

<h3>The types of circuit.</h3>

Basically, the components of an electrical circuit can be connected or arranged in two forms and these are;

  • Series circuit
  • Parallel circuit

<h3>What is a parallel circuit?</h3>

A parallel circuit can be defined as an electrical circuit with the same potential difference (voltage) across its terminals. This ultimately implies that, the equivalent capacitance (C_{eq}) of two (2) capacitors which are connected in parallel is equal to the sum of the individual (each) capacitances.

Mathematically, the equivalent capacitance (C_{eq}) of an electrical circuit containing four capacitors which are connected in parallel is given by this formula:

Ceq = C₁ + C₂ + C₃ + C₄

Substituting the given parameters into the formula, we have;

Ceq = 10 F + 3 F + 7 F + 1 F

Equivalent capacitance, Ceq = 21 F.
