The structures that are surrounding the small intestine in the image are: stomach, ascending colon, cecum and appendix.

<h3>What is the small intestine?</h3>

The small intestine will be part of the digestive system and it is the smallest part of the intestine, it will be after the stomach and before the ascending colon. It will be made up of three parts: duodenum, which is the one attached to the stomach, ileum, and jejunum.

Each of its parts is going to have certain specific functions related to digestion, absorption and have immunity as a function.

Among the characteristics of the small intestine, absorption stands out since its surface is created for better absorption, since it will have circular folds, intestinal villi and microvilli. These will increase the absorption surface, so it works better.

You push your couch a distance of 3.9 m across the living room floor with a horizontal force of 220.0 n. the force of friction i

Mrac [35]

The general formula to calculate the work is:

$W=Fd \cos \theta$

where F is the force, d is the displacement of the couch, and $\theta$ is the angle between the direction of the force and the displacement. Let's apply this formula to the different parts of the problem.

(a) Work done by you: in this case, the force applied is parallel to the displacement of the couch, so $\theta=0^{\circ}$ and $\cos \theta=1$ , therefore the work is just equal to the product between the horizontal force you apply to push the couch and the distance the couch has been moved:

$W=Fd=(220.0 N)(3.9 m)=858 J$

(b) work done by the frictional force: the frictional force has opposite direction to the displacement, therefore $\theta=180^{\circ}$ and $\cos \theta=-1$ . Therefore, we must include a negative sign when we calculate the work done by the frictional force:

$W=-Fd=-(144.0 N)(3.9 m)=-561.6 J$

(c) The work done by gravity is zero. In fact, gravity (which points downwards) is perpendicular to the displacement of the couch (which is horizontal), therefore $\theta=90^{\circ}$ and $\cos \theta=0$ : this means
