Two Questions (Please Answer BOTH): 1. Which is an example of a scientific theory?

A. A scientist explains that the area of a rectangle is proportional to the width times the length or A= wl.
B. A scientist explains that the force acting on an object is equal to the mass times the acceleration, or F= ma.
C. A scientist thinks a purple moth and butterfly are the same species because they look alike.
D. Scientists agree that Earth's axis is tilted. This explains why there are seasons.

2. Which is an example of a scientific law?

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
