An individual picks up a cup and drinks from it. this is an example of
a. a concentric contraction because muscles cause the elbow joint and arm to move
b. an eccentric contraction because the release of the muscle in the back of the arm causes the elbow to bend
c. an isometric contraction because the cup was stationary until the hand picked it up
d. a midcentric contraction because the movement took place around the core of the body
select the best answer from the choices provided. a b c d

A

Explanation:

The correct answer is: A) "A concentric contraction because muscles cause the elbow joint and arm to move"

A. a concentric contraction because muscles cause the elbow joint and arm to move.

Explanation:

Contraction is the phenomenon in which the muscles of our body get activated by the tension produced. When the muscle of our body shortens, caused by the tension applied on our muscle is called concentric contraction. The force produced by the muscle as it shortens bring the cup near our body. There it is an example of concentric contraction.

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

i'm pretty sure its b i might be wrong though!
