Answer: Having a non-functional vestibular apparatus.
Explanation:
Motion sickness is a feeling of sickness that is caused by the movement. It occurs in a vehicle like boat, car, train or bus. It can also occur in the amusement rides. This is not life-threatening. It can make the ride or traveling unpleasant. Motion sickness happens when the brain receives the disturbing message related to the motion and the body's position. These messages are delivered from the ear, eyes, skin receptor, muscles and the joints sensors.
Among the options given, Having a non-functional vestibular apparatus. is not the associated with the development of motion sickness. The vestibular apparatus is associated with ear if the ear sensory system becomes non-functional then it will reduce the sensing of motion sickness.

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
