Material medium electric waves
For number 11, you should say that there is more pollution and fossil fuels being burned.
Answer:
Got it from g00gle: Similarly, electrons flow more easily through a thick wire than they flow through a thin wire of the same material. Resistance is greater in a longer wire because the charges travel farther. As temperature increases, a metal's resistance increases because electrons collide more often.
Explanation:
<h2>A)</h2>
The forces acting on you are:
- The gravitational pull of the Earth (an others Celestial objects)
- The Normal Force that balance the gravitational pull and points upward.
That is. There is not need for any other force, cause the car its going at constant speed, so the acceleration its zero, as the net force its mass multiplied by acceleration, the net force is zero.
<h3>B)</h3>
The forces acting on you are:
- The gravitational pull of the Earth (an others Celestial objects)
- The Normal Force that balance the gravitational pull and points upward.
That is. Again. The car its slowing down. But, it cant apply a force in you against the direction of movement to slow you down.
<h3>C)</h3>
As you can't be slowed down, you will go forward at the same speed you had when the car went steady, and will crash against whatever its in front of you.
D)
The friction force, will pull you against the direction of movement, and slow you down will the car slows down.
