The earth would not be considered a closed system. A closed system is a place or a habitat that is self sustaining and does not require any outside help or force. A closed system requires air food water or anything that any organism inside the system would need the earth is not a closed system because humans can easily leave or enter earth via a space ship as well as asteroids crash landing inside earth would be considered as entering. A biosphere is a ultimate closed system (A biosphere is a self sustaining sphere with plants to make air with any other organisms to create carbon dioxide *look up biospheres for more info*)

Earth is considered a closed system because only energy, not matter, is exchanged. A closed system like Earth can be easily represented by a sealed jar. When the lid is sealed, matter like air or water can neither enter nor exit the jar. If you placed that same jar in a 100-degree oven, the air inside the jar would eventually increase in temperature to 100 degrees, representing an exchange of energy known as heat.

A typical atomic polarizability is 1 × 10-40 (C·m)/(N/C). If the q in p = qs is equal to the proton charge e, what charge separa
Alenkasestr [34]

Answer:

s = 6.25 10⁻²² m

Explanation:

Polarizability is the separation of electric charges in a structure, in the case of the atom it is the result of the separation of positive charges in the nucleus and the electrons in their orbits, macroscopically it is approximated by

                p = q s

               s = p / q

let's calculate

              s = 1 10⁻⁴⁰ / 1.6 10⁻¹⁹

              s = 0.625 10⁻²¹ m

              s = 6.25 10⁻²² m

We see that the result is much smaller than the size of the atom, therefore this simplistic model cannot be taken to an atomic scale.

How do I figure out this
ahrayia [7]
The Atomic Number is equal to the amount of Protons and Electrons. To find the amount of Neutrons in an atom, you have to look at the Mass Number. The Mass Number is the SUM (_+_=_) of Protons and Neutrons in an atom. In this case, you will have to make up equations. For example: Argon. Argon's Mass Number is 40. You need to find the amount of Protons in the atom (18). Mass Number (40) - Protons (18) = Amount of Neutrons. 40-18=22.
Argon has 22 Neutrons, because Protons(18)+Neutrons(22)=Mass Number(40).

Hope I could help!
