When are theories constructed? A. after data is collected from an experiment
B. after there is numerous data collected during the experiment

Hi, This is the answer...

Theories are constructed after there is numerous data collected during the experiment.

Hope it helps you...Pls mark brainliest if it helps you(by Benjemin)

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
