Use the image above and describe the
Lina20 [59]

Answer:

If you see in the image above, there is an unbalance force applied while playing tug of war. Since it is 1 vs 2, there is a greater net force in the right side then the left side. If it was 2 vs 2 or 1 vs 1, then they are appling balance force. You can also see in the picture that the arrows are pointing outwards (--->) rather then inwards (<---) because you are pulling the rope not pushing the rope. If you add one person on the left side, then the newtons which is 20N will become to 35N and will be balanced, but since there in only 1 person, there is less force on the left side, the newtons gets subtracted having only 20N. Since you are pulling the rope, the friction is opposite (<---). Since you are pulling the rope, you are using Kinetic force and the rope stays in potential force since it stays constant.

Hope this helps, thank you :) and I am not sure about magnitude I think you can that since there is greater force on the right side, there is more magnitude there.

HEEEEELP ASAPP IM AWARDING 30 points!!!!

Answer:

\rm S^{2-}.

Explanation:

Based on the electron configuration of this ion, count the number of electrons in this ion in total:

2 + (2 + 6) + (2 + 6) = 18.

Each electron has a charge of (-1).

Atoms are neutral and have 0 charge. However, when an atom gains one extra electron, it becomes an ion with a charge of (-1). Likewise, when that ion gains another electron, the charge on this ion would become (-2).

The ion in this question has a charge of (-2). In other words, this ion is formed after its corresponding atom gains two extra electrons. This ion has 18 electrons in total. Therefore, the atom would have initially contained 18 - 2 = 16 electrons. The atomic number of this atom would be 16.

Refer to a modern copy of the periodic table. The element with an atomic number of 16 is sulphur with atomic symbol \rm S. To denote the ion, place the charge written backwards ("2-" for a charge of (-2)) as the superscript of the atomic symbol:

\rm S^{2-}.
