Question

a student places five books next to each other on their ends. she then pushes the first book with her finger, and a few seconds later, the last book falls. which statement is correct about this chain of events? (1 point) there is a positive correlation between the force of the finger and number of books. the force of the finger causes the books to accelerate and fall. the acceleration of the books as they fall causes the force of the finger. there is causation between the force of the finger and the number of books.

Explanation:

According to Newton's second - law of motion ($F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration), when the student applies a force with her finger on the first book, this force is transferred through the books. The force causes the books to accelerate and eventually the last book falls. There is no correlation or causation between the force of the finger and the number of books in the way described in the other options. The force of the finger is the cause of the books' acceleration and subsequent falling.

Answer:

The force of the finger causes the books to accelerate and fall.
