Question

21.3 quiz: the scientific revolution
sarah has her mother drop both weights at the same time from a window. to her surprise, the weights land at exactly the same time. she repeats the experiment several times, but the weights always hit the ground at the same time. sarah is forced to admit that she was wrong; an objects weight does not affect how fast it falls.
a. \she hopes to prove that heavier objects fall faster than lighter ones.\
b. \an objects weight does not affect how fast it falls.\
c. \sarah wants to create an experiment to determine whether an objects weight determines how fast it will fall.\
d. \she has her mother drop both weights at the same time from a window.\

Explanation:

The text describes Sarah's experiment to test the relationship between an object's weight and its falling - speed. The conclusion of her experiment is that an object's weight does not affect how fast it falls. The hypothesis is the initial idea or prediction before the experiment. Here, she likely hoped to prove that heavier objects fall faster, which is a common misconception before conducting such an experiment.

Answer:

A. "She hopes to prove that heavier objects fall faster than lighter ones."
