Answer: True
Explanation:
It should be noted that when refrigerant is added in vapor form to the operating refrigeration system, then the addition of the refrigerant should be to the low-pressure side of the refrigeration system.
Furthermore, when system pressures are lower than the pressure in the refrigerant tank as stated in the question, then the refrigerant can be added to both the high and low pressure sides of the system.
Therefore, the correct option is true.
Answer: nuclear energy
Explanation: nuclear energy
The ocean's water's density increases when it gets colder.
The molecules in the water get colder and move less, causing it to densify... As though it were freezing (though we all know the ocean hasn't ever frozen)
Explanation:
Orbital period = 2 x 10⁶s
Total radius = 2.5 x 10¹²m
Unknown:
Tangential speed of the satellite = ?
Solution:
The tangential speed simply expresses the rate at which the distance moves around its orbit with time.
Since the orbit is taken to be circular;
Tangential speed = 
r is the radius
t is the time or orbital radius
Tangential speed = ![\frac{2 x 3.14 x 2.5 x 10¹²}{2 x10[tex]^{6}](https://tex.z-dn.net/?f=%5Cfrac%7B2%20x%203.14%20x%202.5%20x%2010%C2%B9%C2%B2%7D%7B2%20x10%5Btex%5D%5E%7B6%7D)

Tangential speed = 7.85 x 10⁶m/s
