Answer:
Modern communication has made our socio-economic life so much better and easier. It is easier now to communicate with someone far away on another continent and even do business and shop online without been physically present at the other end. One of the most important modern means of communication is the internet which has turned the world to a small global village.
<h2>Answer: Mercury</h2><h2 />
The Mariner 10 probe was launched by NASA on November 3rd, 1973, with the purpose of exploring the characteristics of two planets in the solar system that were closest to the Sun, Mercury and Venus.
In addition, it was launched to explore the atmosphere and surface of both planets and <u>prove that it was possible to use gravitational assistance</u> (also called <u>slingshot effect</u>, a special orbital maneuver in order to use the gravitational field energy of a planet or massive body to accelerate or slow the probe and change the direction of its trajectory) in long interplanetary trips to save fuel.
In this case, <u>Mariner 10 first arrived at Venus</u> and succeded in using its gravitational field to accelerate its trajectory towards Mercury.
Answer:
Explanation:
Since the field lines are parallel and the electric field is uniform between two parallel plates, a test charge would experience the same force of attraction or repulsion no matter where it is located in the field,
I attached an image that could help to understand the representation of the field. The formula used to calculate it is given by,
(1)
If we want to consider the change in Voltage with respect to the position then it would be,
According to the information provided, the potential is 
and there is a distance d, therefore
(2)
Taking equation (1) we can clear V, to what we have,
Integrating,
Substituting (2)
Where x is the height from the grounded plate.
I believe the answer is C: For objects at extremely fast speeds.
Hope this helps!
