**Answer:** **539.4 N**

**Explanation:**

Let's begin by explaining that Coulomb's Law establishes the following:

"The electrostatic force between two point charges and is proportional to the product of the charges and inversely proportional to the square of the distance that separates them, and has the direction of the line that joins them"

What is written above is expressed mathematically as follows:

**(1)**

Where:

is the electrostatic force

is the Coulomb's constant

and are the electric charges

is the separation distance between the charges

Then:

**(2)**

Isolating and :

**(3)**

**Now, if we keep the same charges but we decrease the distance to , (1) is rewritten as:**

**(4)**

**Then, the new electrostatic force will be:**

**(5) As we can see, the electrostatic force is increased when we decrease the distance between the charges.**

<span>a. KE in electron volts is 1020 eV.

b. KE in Joules is e(1020) = (1.6022E-19)(1020) = 1.634E-16

**c. KE = (1/2)mv^2, so v = sqrt[2*KE/m] = 18.94E6 m/s**

note: m is the mass of an electron = 9.109e-31 kg

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

600/3 = 200

the slope is 200m/min

OR

600/ (3/60) =

600 x 60/3 =

600 x 20 = 12,000 meters per hour

**B: an increase in acceleration caused an increase in force. **

This is based on the **concept of force** on an object.

Now, **formula** for force is commonly known as;

**Force** = mass × acceleration

Now, mass and acceleration are the input values that make the output which is the Force to either increase or decrease.

- Now, for the line of dominoes to fall, it means that the force was so overwhelming that the dominoes couldn't resist it.

Now, this output which is the force became so much as a result of the increase in acceleration of the motion that triggered its movement.

Moreover, the force is **directly proportional** to the acceleration!

Thus, we can say that an increase in acceleration caused an increase in force.
