What is the electric force acting between two charges of -0.0045 C and -0.0025 C that are 0.0060 m apart? Use Fe=kq1q2/r^2 and k
oksano4ka [1.4K]

Answer:

D. 2.8 × 10⁹ N

Explanation:

The force between two charges is directly proportional to the amount of charges at the two points and inversely proportional to the square of distance between the two points.

Fe= k Q₁Q₂/r²

Q₁= -0.0045 C

Q₂= -0.0025 C

r= 0.0060 m

k= 9.00 × 10 ⁹ Nm²/C²

Fe= (9.00 × 10 ⁹ Nm²/C²×-0.0045 C×-0.0025 C)/0.0060²

=2.8 × 10⁹ N

If 12V battery maintains a 4.5A current through a resistor what is the resistance of the resistor?
Dimas [21]

Answer:

2.7ohms

Explanation:

Given parameters:

Voltage of the battery  = 12V

Current  = 4.5A

Unknown:

Resistance of the resistor  = ?

Solution:

From Ohm's law, we know that;

          V  = IR

V is the voltage

I is the current

R is the resistance

  So;

        R  = \frac{V}{I}   = \frac{12}{4.5}    = 2.7ohms
