1. Newton's second law says how quickly an object accelerates is directly related to the mass of the object and the
O length of the object
O location of the object
O the force applied to it
O direction the object is going

An objects accelarates in the same direction as that of the force applied.

Explanation:

a. hope i'm right

explanation:

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
