Give me Argon's Atomic Number

How many valence electrons does this element have?

The formula for Force is

• F= MxW

• F= MxA

• F=MxT

Answer explanation

The correct formula for Force is F= MxA, where Force equals Mass multiplied by Acceleration.

Newtons 3rd Law explains 

• For every action, there is an opposite but equal reaction

• F= MxA

• Inertia

• An object in motion stays in motion unless acted upon by an outside force

Answer explanation

Newton's 3rd Law states that for every action, there is an opposite but equal reaction, explaining the relationship between forces in a system.

An object remains in constant motion, weather that motion is rest, or actual movement.

• Inertia 

•  Gravity

• Force

Answer explanation

Inertia is the correct choice because it is the property of matter by which it remains in constant motion, whether at rest or moving.
