Newton's third law (for every action, there is an equal and opposite reaction) means that in every interaction (in this case, that of the objects in the image), there is a pair of forces acting on the two interacting objects. <span>When you sit on a chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body. This is embodied in the image by the two objects exerting force on each other (indicated by the arrows).</span><span>

Answer: Kinetic Energy is already moving and is not at rest. Potential Energy is purely based on the position of the object and also the condition of the object.

Answer:
An atom of Al which has 13 protons and 10 electrons is Al cation (Al⁺³)
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other.
For example,
Al atom has 13 protons and 13 electrons. The number of positive and negative charge is equal thus it will be neutral atom.
While the atom of Al which have 13 proton and 10 electron is not neutral. The positive charge is greater than negative by 3. Which means 3 electrons are lose by Al atom and form cation "Al⁺³".
Thus an atom of Al which has 13 protons and 10 electrons is Al cation (Al⁺³)
Answer:
V₂ = 6.0 mL
Explanation:
Given data:
Initial volume = 9.0 mL
Initial pressure = 500 mmHg
Final volume = ?
Final pressure = 750 mmHg
Solution:
According to Boyle's Law
P₁V₁ = P₂V₂
V₂ = P₁V₁ / P₂
V₂ = 500 mmHg × 9.0 mL / 750 mmHg
V₂ = 4500 mmHg .mL / 750 mmHg
V₂ = 6.0 mL
