Fromula for calculating mass when density and volume are given is as m=ρV mass of blood = 1.05 × 2 mass of bag of blood = 2.15 kg
To solve this problem we will use the mathematical definition of the light years in metric terms, from there, through the kinematic equations of motion we will find the distance traveled as a function of the speed in proportion to the elapsed time. Therefore we have to
means Light Year
Then
![14.4Ly = 1.36231609*10^{17} m](https://tex.z-dn.net/?f=14.4Ly%20%3D%201.36231609%2A10%5E%7B17%7D%20m)
If we have that
![v= \frac{x}{t} \rightarrow t = \frac{x}{t}](https://tex.z-dn.net/?f=v%3D%20%5Cfrac%7Bx%7D%7Bt%7D%20%5Crightarrow%20t%20%3D%20%5Cfrac%7Bx%7D%7Bt%7D)
Where,
v = Velocity
x = Displacement
t = Time
We have that
= Speed of light
![t = \frac{1.36231609*10^{17}}{0.96(3*10^8)}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B1.36231609%2A10%5E%7B17%7D%7D%7B0.96%283%2A10%5E8%29%7D)
![t= 454105363 s (\frac{1hour}{3600s})](https://tex.z-dn.net/?f=t%3D%20454105363%20s%20%28%5Cfrac%7B1hour%7D%7B3600s%7D%29)
![t= 126140 hours(\frac{1day}{24hours})](https://tex.z-dn.net/?f=t%3D%20126140%20hours%28%5Cfrac%7B1day%7D%7B24hours%7D%29)
![t= 5255.85 days(\frac{1 year}{365days})](https://tex.z-dn.net/?f=t%3D%205255.85%20days%28%5Cfrac%7B1%20year%7D%7B365days%7D%29)
![t = 14.399 years](https://tex.z-dn.net/?f=t%20%3D%2014.399%20years)
Therefore will take 14.399 years
Meteoroid
Streak of light
Reached earth's atmosphere
Explanation:
The celestial object is called a meteoroid because it is a producing a streak of light and has not yet reached the earth's atmosphere.
Meteoroids are called shooting stars due to the beautiful trail of light they leave in their wake.
- A meteoroid is a celestial object that ranges from a few grains to some meters wide.
- They are usually solid. They can be rocky, metallic or both.
- A meteoroid is still in space and has not reached the earth atmosphere.
- Some meteoroids are destroyed when they get to the atmosphere and are called meteors.
- Those that penetrates and reaches the surface are called meteorites.
