A team of students performs an experiment to test the effect of gravity on different objects with the same mass. They measure how long it takes the objects to fall from the top of the school’s bleachers. How can they insure they get accurate data?(1 point)

by repeating the experiment several times
By erecting a pipe from the bleacher top to the ground and connecting it to a vacuum pump to get the air out of it.
While creating a vacuum environment may technically eliminate the effect of air resistance on the falling objects, it is not a practical or necessary step to ensure accurate data in this context. The standard procedure of repeating the experiment several times and using proper timing equipment would still be sufficient to get accurate data on the effect of gravity on the objects.
