Answer:
<u> </u><u>The magnitude of the force exerted by the biceps </u>
<u> is 218.38N</u>
<u>The magnitude of the force exerted by the elbow </u>
<u> is 194.37N</u>
Explanation:
Firstly , lets calculate the magnitude of force exerted by biceps
-
Mass of the forearm=

Mass of the ball =

= 0.950kg
so, weight of the forearm=
g
weight of the ball=
g
Now , balancing torque about the elbow , we have-

(here , distance of the bicep is 2.50cm = 0.025m and distance of the ball is 36cm= 0.36m)
Now putting the given values in the formula -


Now, lets calculate the force exerted by elbow
-
Balancing the vertical forces



Is this not about a human? We only have one aortic arch
Answer:
The root.
Explanation:
The root must be the damaged part of the plant. This is because the root har cells are on the root and no new root cells are produced.
Thank you
All of the above.
A multicellular organisms is any living this that is made up of more than one cell. Insects, humans and flowers are all made up of microscopic cells that each serve it's own purpose in supporting life.
An example of a single celled organism would be bacteria. They are a very basic living thing only made up of a single cell.
Hope this helps!
