Answer: At the point when space experts take a gander at an article's range, they can decide its arrangement dependent on these frequencies. The most well-known technique stargazers use to decide the sythesis of stars, planets, and different articles is spectroscopy. This spread-out light is known as a range.
Explanation:
Yo sup??
Solenoids are a kind of bar magnet.
The have low coercivity and low retentivity
The are made by taking a soft iron core and covering it with a coil.
Hope this helps.
525L
Explanation:
Given parameters:
Volume to Temperature ratio = 1.75
Temperature = 300k
Unknown:
Volume of the gas = ?
Solution:
We must carefully analyze and comprehend the detailed description of this experiment:
It was suggest that the gas could expand or shrink without changing the pressure of the gas inside.
This implies that the pressure in the vessel is constant
This similar to the postulate of the Charles's law: The volume of a fixed mass of gas is directly proportional to the absolute temperature if the pressure is constant.
Mathematically;

V and T are the volume and temperature
Now we can solve the given problem;
= 1.75
Since temperature is given as 300K
Input the variables:
= 1.75
V = 1.75 x 300 = 525L
