you weight 650 N. What would you wieght if the Earth were four times as massive as it is and its raduis were three times its pre
LiRa [457]

To solve this problem we will apply the concept given by the law of gravitational attraction, which properly defines gravity under the function

g = \frac{GM}{r^2}

Here,

G = Gravitational Universal Constant

M = Mass of Earth

r = Distance between the human and the center of mass of the Earth

The acceleration due to gravity when is 4 times the mass of Earth and 3 times the radius would be given as,

g_1 = \frac{GM}{r^2}

g_2 = \frac{G(4M)}{(3r)^2}

g_2 = \frac{4GM}{9r^2}

g_2 = \frac{4}{9} g_1

The weight is defined as

W = mg_1

So the new weight would be given as

W' = mg_2

W' = m(\frac{4}{9} g_1 )

W' = \frac{4}{9} mg_1

W' = \frac{4}{9} W

W' = \frac{4}{9}(650)

W' = 288.8N

Therefore the weight under this condition is 288.8N

Correctly label the following structures surrounding the small intestine. Stomach Appendix lleum Cecum Jejunum Ascending colon
kifflom [539]

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.
