Which statement correctly lists the four forces from the weakest to the strongest?

2 answers:

4 0

The strongest of the natural forces is Strong Nuclear, followed by Electromagnetic, then Weak Nuclear and lastly Gravitational.
So from weakest to strongest: gravitational --> weak nuclear --> electromagnetic --> strong nuclear
Answer C)

The correct answer of this question is : C i.e Gravitational < Weak nuclear force < Electromagnetic force < Strong nuclear force.

EXPLANATION:

There are four fundamental forces in nature which are known as gravitational force, weak nuclear force, electromagnetic force and strong nuclear force.

Out of these four fundamental forces, the gravitational force is the weakest forces in nature,but has infinite range.

Weak nuclear force is produced due to W/Z bosons. Hence, it is stronger than gravitational force but weaker as compared to electromagnetic and strong nuclear force. It is a short range force.

Electromagnetic force is the third one which is weaker as compared to strong nuclear force but has infinite range.

Strong nuclear force is a short range, spin dependent strong attractive force that arises between nucleons due to exchange of mesons.

Research the potential for a large earthquake off the coast of Oregon. What are two of the biggest concerns with a large earthqu

Sphinxa [80]

There is a 33% chance of a large earthquake off the coast of Oregon.

The two main concerns of a large earthquake are Gas fires and Tsunami .

Explanation:

Everytime a large earthquake hits in any other part of the world, We find a small earthquake hitting off the coast of Oregon.

So scientists feel that as United States is prone to Earthquakes, the people have to be prepared for such eventualities.

The main concern for this large earthquake is, that it might lead to gas leakages at homes that can start a gas fire, which might spread. So people have to be careful and check on any gas leakages.

Such large earthquakes can also lead to tsunami waves. So people have to take precautions and evacuate, if they are near the coastline.

Two spectators at a soccer game in Montjuic Stadium see, and a moment later hear, the ball being kicked on the playing field. Th

Akimi4 [234]

Answer:

a) The distance of spectator A to the player is 79.2 m

b) The distance of spectator B to the player is 43.9 m

c) The distance between the two spectators is 90.6 m

Explanation:

a) Knowing the time it takes the sound to reach both spectators, we can calculate their position relative to the player, using this equation:

x = v * t

where:

x = position of the spectators

v = speed of sound

t = time

Then, the position for spectator A relative to the player is:

x = 343 m/s * 0.231 s = 79.2 m

b)For spectator B:

x = 343 m/s * 0.128 s

x = 43.9 m

The distance of spectator A and B to the player is 79.2 m and 43.9 m respectively.

c) To calculate the distance between the spectators, please see the attached figure. Notice that the distance between the spectators is the hypotenuse of the triangle formed by the sightline of both. We already know the longitude of the two sides. Then, using Pythagoras theorem:

(Distance AB)² = A² + B²

(Distance AB)² = (79.2 m)² + (43.9 m)²

Distance AB = 90. 6 m
