What law states that for every action there is an equal and opposite reaction?
A. Law of Inertia
B. Law of Accelaration
C. Law of Interaction
D. Newton's First Law
C. Law of Interaction
His third law states that for every action (force) in nature there is an equal and opposite reaction. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A. In other words, forces result from interactions.

400
Which of the following speeds is faster?
A. The speed of sound
B. The speed of light
C. The speed of electricity
D. The speed of water
B. The speed of light
Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second). Only massless particles, including photons, which make up light, can travel at that speed. It's impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so.
