Answer:
The volume is 
Explanation:
From the question we are told that
The depth below the see is 
The density of the sea is 
The temperature at this level is 
The volume of the air bubble at this depth is 
The temperature at the surface is 
Generally the pressure at the given depth is mathematically evaluated as
Where 
is the atmospheric pressure with a constant value
substituting values
According to the combined gas law
=> 
=>
Assuming that the magnitude is additive, then you simply have to add the brightness four times. This is because each star has 2 magnitudes of 8.34. As a result, you have to add 4 magnitudes of 8.34. The solution is as follows:
Magnitude = 4(8.34)
Magnitude = 33.36
Oil, plexiglass, then water
Since the formula is mass/volume the density is 3.4915......g/cm^3
Answer:
According to <em>Newton's first law of motion:</em>
<u>An object in motion tends to remain in motion unless an external force acts upon it.</u>
<u>It stays in motion with the same speed and goes in the same direction.</u>
