The correct answer is: tighten and contract
This is is the correct
answer because muscle fibers need to first reach an optimal length and
tension ratio or "tighten" in order for the muscle to perform work.
After the muscle has tightened, it can then "contract" which leads to a
decrease in the angle of the joint through force. If the muscle being
used to pull the rope is the bicep on the arm, then the angle between
the forearm and upper arm will decrease, causing the rope to be pulled.
Answer:
0.3 m
Explanation:
When a person is myopic it means that light rays from distant object are focused in front of retina so in order to correct this, we use concave lens. The concave lenses focuses these rays on the retina.
Wearing glasses will not change the eye in any way. The diverging lens is simply used to form an image of the object at a distance where the myopic person can see it clearly. Another myopic individual that is not wearing a lens can see clearly objects that fall between their near point and their far point, as well as an individual wearing glasses can see images that fall between their near point and their far point.
Lens' power= -3 diopters = 1/ focal length,f.
Therefore, f= 1/-3 = - 0.3
Far point = -(-0.3) = 0.3 m
The word <em>intravenous</em><em> </em>means "vein", therefore the drug is injected directly into Katy's vien.
