Answer:Visible light communication (VLC) is a wireless method that uses light emitted by LEDs to deliver networked, mobile, high-speed communication similar to Wi-Fi, leading to the term Li-Fi. It can be used as standalone solution or in a supplementary role to radio-frequency (RF) or cellular network communication
Explanation:
<h2>According to Newton's Third Law:</h2><h3>"For every action,there exists an equal and opposite reaction"</h3>
<h3>So an action force of 50 N to the left, results in a 50 N reaction force to the right.</h3>
<h2>Option A</h2>
To solve the problem it is necessary to have the concepts of the magnetic field in a toroid.
A magnetic field is a vector field that describes the magnetic influence of electric charges in relative motion and magnetized materials.
By definition the magnetic field is given by the equation,
Where,
= Permeability constant
N = Number of loops
I = Current
r = Radius
According to the given data we have that the length is 120mm and the thickness of the copper wire is 4.82mm.
In this way the number of turns N would be
On the other hand to find the internal radius, we know that:
Therefore the total diameter of the soda would be
Applying the concept related to magnetic field you have to for the internal part:
The smallest magnetic field would be on the outside given by,
<em>Therefore the maximum magnetic field is 0.06T.</em>
The bomb strike the ground relative to the point at 1km . B
<h3>How to determine the distance</h3>
Using the equation
h = 1/2 gt^2
500 = 1/2 * 10* t^2
500 = 5t^2
t = √500/5
t = √100
t = 10seconds
To find the distance,
Distance = velocity * time
Distance = 100 ÷ 10
Distance = 1000m = 1km
Therefore, the bomb strike the ground relative to the point at 1km . B

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.
