What makes an electric charge?

2 answers:

Answer:

Most electric charge is carried by the electrons and protons within an atom. Conversely, two protons repel each other, as do two electrons. Advertisement. Protons and electrons create electric fields, which exert a force called the Coulomb force, which radiates outward in all directions.

What is the change in momentum of a 0.18 kg arrow that is traveling at 100 m/s and is stopped by a hay

Kryger [21]

The 2 seconds part isn’t relèvent to the question.
So momentum = mass x velocity
So 0.18 x 100 = 18

3. A wye-connected load has a voltage of 480 V applied to it. What is the voltage dropped across each phase?

ZanzabumX [31]

Answer:

$E_s = 277.13V$

Explanation:

Given

$Load\ Voltage = 480V$

Required

Determine the voltage dropped in each stage.

The relation between the load voltage and the voltage dropped in each stage is

$E_l = E_s * \sqrt3$

Where

$E_l = 480$

So, we have:

$480 = E_s * \sqrt3$

Solve for $E_s$

$E_s = \frac{480}{\sqrt3}$

$E_s = \frac{480}{1.73205080757}$

$E_s = 277.128129211$

$E_s = 277.13V$

<em>Hence;</em>

<em>The voltage dropped at each phase is approximately 277.13V</em>

What is the equivalent resistance of the circuit?

Zigmanuir [339]

Answer:

5.5Ω

Explanation:

The circuit diagram shown is a parallel arrangement. To solve this problem for the equivalent resistance,

R1 = 10Ω

R2 = 20Ω

R3 = 30Ω

For circuits in parallel, equivalent resistance is ;

$\frac{1}{Rt}$ = $\frac{1}{R1} + \frac{1}{R2} + \frac{1}{R3}$

Now insert the parameters and solve;

$\frac{1}{Rt}$ = $\frac{1}{10} + \frac{1}{20} + \frac{1}{30}$

$\frac{1}{Rt}$ = $\frac{6 + 3 + 2}{60}$

$\frac{1}{Rt}$ = $\frac{11}{60}$

Rt = 5.5Ω

Which pair does NOT have an electric force between them?

fenix001 [56]

Answer:

Two Neutral

Explanation:

If; One postive, and one negative they would be attracked. >-<

If; one postive and the other was postive, (or vice versa) they would repel <->

they both have an electrical charge, and force.

Neutral's are Nueatral. they have to opisition or attraction= No electrical force.
