Its 2.1, I just took the test, the verified answer is wrong.
Answer:
The terminal velocities will be the same in a vacuum and different for the egg and further.
Explanation:
Thinking process:
The terminal velocity is the maximum velocity that an object can attain after overcoming the resistance caused by the atmosphere or air. In other words, the velocity equation is given as:
where F is the net force,
D = Drag force
W = Weight of the object falling down.
The drag force increases by the increase with the square of the velocity like this:
The terminal velocity is given by the equation:
V = Sqrt (2W/CdpA)
In the absence of friction, like a vacuum, the velocities are the same.
In the atmosphere, there is drag, and the velocities are different.
Answer
atoms or molecules
Explanation
A pure gas such as argon or neon is made up of individual atoms. Other compound gasses such as oxygen or carbon dioxide are made up of elements.
Protons, neutrons and electrons are parts of an atom. They are not actually particles but charges.
The answer to the question is atoms or molecules.

Answer: 14.7 N
Explanation:
The weight of an object on Earth is given by
where
m is the mass of the object
is the acceleration due to gravity on Earth's surface
In this problem, we have a book of mass m=1.5 kg, so its weight is given by
