My Friday is going good and I might get to go over to my BFF house!!!
Given what we know, we can confirm that if you aimed light from the magenta part of the Horsehead Nebula through a spectrograph we would be able to determine more precisely the structure and details of the cloud.
<h3>How do we use Spectrums in order to understand stars?</h3>
The spectrums recorded by scientists, such as those of stars or nebulas like the horsehead nebula can tell us a great deal about the composition of said entities. Studying the spectrum can tell scientists about the chemical composition of stars or nebulas, such as information about the elements that form them, like their temperatures and densities.
<h3 /><h3>How would a discontinuous emission of hydrogen gas look in the spectrum?</h3>
This would appear as pauses in the lines of the spectrum. If the emission of the hydrogen gas were constant, there would be a continuous line on the spectrum graph to indicate the illuminated hydrogen, though if this line were discontinuous, we would be able to assume that its source is emission from another gas instead.
Therefore, we can confirm that spectrography is an essential part of scientific discovery pertaining to our universe. It allows us to study the chemical composition of stars and nebulas, and determine the sources of certain emissions like that of hydrogen gases.

Answer: The correct answer is Option C.
Explanation:
We are given a piston of a pump, which means that there is no loss of the air. and there is a change in pressure and volume but temperature of the system remains constant.
As, the pressure of the system increases, there will be more number of particles. So, the number of collisions per unit area will increase.
But in the question, volume gets doubled. So, the pressure will be determined by using Boyle's Law:
where, 
are the initial and final volume respectively.
Putting the change in volume in above equation, we get:
where, 
are the initial and final pressure respectively.
As, the pressure is reduced to half of the initial pressure. So, the number of collisions per unit area will also be reduced to one-half.
Hence, the correct answer is Option C.
This is an example of Charles’ Law problems, the basic equation is: V1/T1 = V2/T2. One vital thing to recall for all gas law problems is that the temperature must be in Kelvin (not Celsius).
So our given is 10.0 C = 283 K. So
V1/T1 = V2/T2
733/283 = 950/T2
T2 = 367 K

I think the turtles won't be able to lays eggs.
I would see the population of turtles reduce overtime.
