Answer: A capacitor.

Explanation:

The capacitor is a passive element that is used in electronics to store electrical energy maintaining an electrical field. The simpler case of a capacitor is the parallel plates capacitor.

It consists of two parallel metal plates separated by a distance D, in this case, the air between the plates works as a dielectric, as the plates do not touch each other and are separated by a dielectric, the charge is stored in the surface plates.

There are a lot of other types of capacitors, the most used in actuality may be the cylindrical one, where instead of parallel plates, it uses two concentric cylinders, and the space between the cylinders is filled with a dielectric/insulator.

2. If a rock fell down a cliff and hit the bottom of the ravine at 4 seconds, how fast was the rock
Iteru [2.4K]

Answer: -39.2 m/s or 39.2 m/s directed downwards

Explanation:

This situation is a good example of Free Fall, where the main condition is that the initial velocity must be zero V_{o}=0, and the acceleration is constant (acceleration due gravity).

So, in order to calculate the final velocity V of the rock just at the moment it hitsthe bottom of the cliff, we will use the following equation:

V={V_{o}}^{2}+gt

Where:

g=-9.8 m/s^{2} is the acceleration due gravity (directed downwards)

t=4 s is the time it takes to the rock to fall down the cliff

V=(-9.8 m/s^{2})(4 s)

V=-39.2 m/s This is the rock's final velocity and its negative sign indicates it is directed downwards

7. When will an object's displacement and distance traveled be different?
mariarad [96]

If an object changes direction while travelling will an object's displacement and distance travelled be different.

Some people believe that distance and displacement are simply different names for the same quantity. However, distance and displacement are not the same thing. If an object changes direction while travelling, the total distance travelled is greater than the displacement between those two points.

The magnitude of the displacement is always less than or equal to the distance because it is measured along the shortest path between two points.

When the direction of displacement does not change, the magnitude of the displacement and distance are the same. When a body travels in a straight line, for example, its displacement and distance are the same.
