A blue star has the hottest temperature.
Answer: Option B
<u>Explanation:
</u>
Stars are composed of gases which ignite themselves and converge in a spherical shape. Their energy is stored in a specific spherical structure depending upon their gravity. Each star has its own gravity formed by the mass of igneous gas combined to form a star.
They illuminate the cosmic area and their lights can travel much longer distances. The stars can be classified based on spectral frequency or the light they are emitting and also based on their temperature. Thus, the star with the coolest temperature is termed as Red stars and the star with the hottest temperature is termed as blue stars.

Answer:
jk
Explanation:
Lets decompose the initial velocity into its components:
Vi = 2.25 m/s
Vix = Vi x cos(50)
Viy = Vi x sin(50) = 2.25 x sin(50) = 1.724
Then decompose the final velocity:
Vf = 4.65
Vfx = Vf x cos(120)
Vfy = Vf x sin(120) = 4.65 x sin(120) = 4.027
After that we can use:
Vfy = Viy + ay*t
ay = (Vfy - Viy)/t
ay = (4.027 - 1.724) / 8.33
ay = 0.276
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.
