Question

which answer shows the fundamental forces in the correct order from strongest magnitude to weakest?

• 20 points

○ weak nuclear force, gravitational force, strong nuclear force, electromagnetic force
○ strong nuclear force, electromagnetic force, weak nuclear force, gravitational force
○ electromagnetic force, strong nuclear force, gravitational force, weak nuclear force
○ gravitational force, electromagnetic force, strong nuclear force, weak nuclear force

once a planet is set in motion within its gravitational environment, it will follow a stable orbital path unless influenced by external forces, such as gravitational interactions with other celestial bodies. this example demonstrates newton’s _______.

• 20 points

○ law of universal gravitation
○ 3rd law of motion
○ 1st law of motion
○ 2nd law of motion

Explanation:

First Question (Fundamental Forces Order)

The fundamental forces in nature, from strongest to weakest magnitude, are: Strong Nuclear Force (binds atomic nuclei), Electromagnetic Force (acts on charged particles), Weak Nuclear Force (involved in radioactive decay), and Gravitational Force (weakest, acts on mass/energy). So the correct order is Strong Nuclear Force, Electromagnetic Force, Weak Nuclear Force, Gravitational Force.

Newton's 1st Law of Motion (Law of Inertia) states that an object in motion stays in motion with constant velocity (or stable orbital path, a type of motion) unless acted upon by a net external force. The planet's stable orbit unless external forces (like other celestial bodies' gravity) act matches this law. The Law of Universal Gravitation is about gravitational attraction, 3rd Law is action - reaction, and 2nd Law is about force, mass, and acceleration ($F = ma$), which don't fit here.

Answer:

B. Strong Nuclear Force, Electromagnetic Force, Weak Nuclear Force, Gravitational Force
