Two opposite forces which are acting perpendicular to an axis cause the moment of couple or torque.
<h3>What is couple?</h3>
Couple is the pair of force of equal magnitude which acts in opposite direction to each other. The moment of couple is known as the troque, which can be calculate as,

Here, (F) is the magnitude of one of the force and (s) is the perpendicular distance of force acting on axis.
Here, the two opposite forces are given which acts perpendicular to an axis. Now suppose there is the magnitude of both the force (F) is equal and the perpendicular distance from the axis is also same.
Thus, from the above definition of moment of couple, they produce, torque or moment of couple.
Hence, the two opposite forces which are acting perpendicular to an axis cause the moment of couple or torque.

There are a lot of ways to test for an hypothesis. There are known five steps of a test of hypothesis through the use of the critical value approach. They are;
- One has to Specify the Null Hypothesis.
- You have to also specify the Alternative Hypothesis.
- Then you set the Significance Level.
- Calculate the Test Statistic and Corresponding P-Value.
- Lastly, Draw a Conclusion.
<h3> The critical value approach?
</h3>
- This is known as a method that involves the determining of the "likelihood" or "unlikelihood" by knowing if or not the observed test statistic is said to be of a more extreme measure than would be expected if the null hypothesis were true.
It often uses the sample data and then there is an assumption if the null hypothesis is true before one can calculate the value of the test statistic.

Answer:
density of the sediment
size of the sediment
velocity of the agent of erosion
Explanation:
The correct answer is - C. A male black bear eats fish in an area of a lake, so other black bears can't.
The intraspecific competition is a competition between the members of the same species for resources and territory. The indirect competition, in this case, would mean that the members from the same species do not get into a direct physical confrontation over the resources, but instead avoid each other and once one member occupies one place, the other one goes to another space that is not occupied.
In this case, with the black bear, the bear has occupied a spot at the lake where it feeds itself. Even though it is using the food resources, the other bears don't physically confront it, but instead pick another place on the lake that is free for using the same food resources.
