If the distance of a force arm (FA) is 4 feet and the resistance arm (RA) is 2 feet, then the mechanical advantage would be

2

Explanation:

From the question, we are informed that the distance of a force arm (FA) is 4 feet and the resistance arm (RA) is 2 feet.

Based on the information given, the mechanical advantage would be calculated as:

= Force Arm / Resistance Arm

= 4 feet / 2 feet

= 2

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
