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
Answer:
The brain cells and skin cells both contain DNA molecules, and their DNA molecules contain the same genetic information. The brain cells and skin cells both contain DNA molecules, but their DNA molecules contain different genetic information.
<span>Herbivores posses different digestive system than that of carnivores. In the course of evolution herbivory evolved with a complex digestive tract. There is no cannine teeth for herbivores. The stomach contains billions of bacteria. The intestine is 27 times longer in length than the length of its body.</span>
