Answer: Only technician A.

Explanation:

A 12 volt battery has 6 cells, where each cell produces around 2 volts.

Now, a battery cell has two sets of plates (or two main plates), one set of negative charged plates and other of positive charged plates, separated by an insulating material. Those plates are related to the amount of energy that can be stored by the battery, not with the voltage it has.

So the only one correct is technician A.

Answer:Technician A

Explanation:

Technician A is right as a 12 v battery contains 6 cells of 2.2 volts and

The size of the battery plates and amount of electrolyte decides the amount of charge lead acid batteries can store for example thus more plates a cell does not mean more voltage it creates.

What is the anion of the ionic compound NaC2H3O2<br><br> thank you!
KIM [24]

C₂H₃O₂⁻ is an anion.

<u>Explanation:</u>

NaC₂H₃O₂(s)   →  Na⁺(aq)  +  C₂H₃O₂⁻(aq)

NaC₂H₃O₂ when dissociated, yields Na⁺ and C₂H₃O₂⁻.

Anion is a negatively charged ion.

In this case,  C₂H₃O₂⁻ is an anion.

A -0.00325 C charge q1 is placed 5.62 m from a second charge q2. The first charge is repelled with a 48900 N force. What is the
blagie [28]

Answer: q2 = -0.05286

Explanation:

Given that

Charge q1 = - 0.00325C

Electric force F = 48900N

The electric field strength experienced by the charge will be force per unit charge. That is

E = F/q

Substitute F and q into the formula

E = 48900/0.00325

E = 15046153.85 N/C

The value of the repelled second charge will be achieved by using the formula

E = kq/d^2

Where the value of constant

k = 8.99×10^9Nm^2/C^2

d = 5.62m

Substitutes E, d and k into the formula

15046153.85 = 8.99×10^9q/5.62^2

15046153.85 = 284634186.5q

Make q the subject of formula

q2 = 15046153.85/ 28463416.5

q2 = 0.05286

Since they repelled each other, q2 will be negative. Therefore,

q2 = -0.05286
