Law makers passed this law to stop drivers from being distracted. I think it will help with drivers safety because it makes the drivers pay attention to the road and almost nothing else.
Surface water becomes groundwater through infiltration.
<h3>What is infiltration?</h3>
Infiltration is a term to refer to the method by which water seeps into the ground to recharge underground water reservoirs. In this process, the water molecules pass through the soil and are grouped in underground water deposits.
<h3>Why is groundwater important?</h3>
Groundwater is important because it is a reservoir of fresh water for consumption. Additionally, these reservoirs help preserve the surrounding vegetation species.

The magnitude of the gravitational force between the two spheres is approximately; F = 1.67 x 10⁻⁹ N
<h3>Gravitational Force</h3>
We are given;
Mass 1; M = 15 kg
Mass 2; m = 15 kg
distance of separation; r = 3 m
Formula for gravitational force using newtons law of gravitation is;
F = GMm/r²
where;
M is mass 1
m is mass 2
G is gravitational constant = 6.67 × 10⁻¹¹ N.kg²/m²
r is distance of separation
Plugging in the relevant values, we have;
F = (6.67 × 10⁻¹¹ × 15 × 15)/3²
F = 1.67 x 10⁻⁹ N

By rewriting the equation from step 1 substituting the value of k into it, the value of x is 22.5
A direct variation is a type of variation that has two types of variables in which a variable can be expressed in terms of the other with its constant.
For example;
If x varies directly as y
<h3>Step 1:</h3>
Then
- x y
- x = ky ; where k is constant
<h3>Step 2:</h3>
The original question says:
- if x varies directly as y, and x = 9 when y = 6, find x when y = 15
∴
x = ky
9 = k × (6)
k = 9/6
k = 1.5
<h3>Step 3:</h3>
Now, we can rewrite the equation from step 1 substituting the value of k into it:
∴
x = ky
The value of (x) will be:
x = 1.5 (15)
x = 22.5

Answer:
Step 1
The expression for the electric force between 2 charges is given as
F=k q1q2/r2
Here
F is the electric force
k is the coulombs constant
q1 is the charge on 1st particle
q2 is the charge on second particle
r is the distance the charges
Step 2
From the above expression we can clearly see that the force has the inverse relation with the square of distance between the charges. So if the distance between the charges increases, force will decrease.
Therefore, when the distance between the object increases, the magnitude of the force decreases.
