if two point charges are separated by 1.5 cm and have charge values of 2.0 and -4.0, respectively, what is the value of the mutu

RUDIKE [14]

Complete question:

if two point charges are separated by 1.5 cm and have charge values of +2.0 and -4.0 μC, respectively, what is the value of the mutual force between them.

Answer:

The mutual force between the two point charges is 319.64 N

Explanation:

Given;

distance between the two point charges, r = 1.5 cm = 1.5 x 10⁻² m

value of the charges, q₁ and q₂ = 2 μC and - μ4 C

Apply Coulomb's law;

$F = \frac{k|q_1||q_2|}{r^2}$

where;

F is the force of attraction between the two charges

|q₁| and |q₂| are the magnitude of the two charges

r is the distance between the two charges

k is Coulomb's constant = 8.99 x 10⁹ Nm²/C²

$F = \frac{k|q_1||q_2|}{r^2} \\\\F = \frac{8.99*10^9 *4*10^{-6}*2*10^{-6}}{(1.5*10^{-2})^2} \\\\F = 319.64 \ N$

Therefore, the mutual force between the two point charges is 319.64 N

What happens to the matter that makes up a liquid when sound travels through it

TiliK225 [7]

Explanation:

The matter passes in the directions of the noise and flows from the source to a receiver like sound flows through a substance. As the sound flows through a fluid, the material is disrupted for an amount of time, but after the sound leaves, it restored to its normal location.

The density (mass/volume) of aluminum is 2.70 mc016-1.jpg 103 kilograms per cubic meter (kg/m3). What is the mass of an aluminum

Masja [62]

The answer is 4.05 × 10³ kg

The density (D) is a quotient of mass (m) and volume (V) of a substance:
D = m/V

Step 1. Calculate the volume o
We have:
D = 2.70 × 10³ kg/m³
V = 1.50 m³
m = ?

D = m/V
m = D * V
m = 2.70 × 10³ kg/m³ × 1.50 m³ = 4.05 × 10³ kg
