Answer:
C
Explanation:
<em>During respiration, oxygen diffuses into the lung (carbon dioxide diffuses out), gets into the blood, and is transported around the body. The hemoglobin of the blood distributes the oxygen to the various cells and carbon dioxide from these cells diffuses into the blood. The blood travels back to the lung where the carbon dioxide is exchanged for oxygen once again. The carbon dioxide is eventually exhaled out of the nose.</em>
The correct option is C.
Answer:
- <u>Translated from Spanish language:</u>
"As part of a vertical shooting test a rock is thrown, with an ancient Roman catapult, vertically upwards with an initial speed of 100m / s."
Explanation:
- As, the motion can be termed as more of a projectile form, while the initial velocity of the projectile or the body in motion is about a 100m/ s. We can easily determine the final velocity, Vf of the body by the following equation given as follows.
- And, let say that the initial time taken is about 2 seconds.So, we can put the values of the gravity, along with the time,t in the following equation and get a valid result for all of this in a more proper way.
- Vy= V(x)- gt, ⇒ V(y)= 100- (9.8)×(2 seconds),
- V(y)= 80.4 m/sec. <u>"</u><u>Answer"</u>
