Do heavier objects fall more slowly than lighter objects?

No. If an object is heavier the force of gravity is greater, but since it has greater mass the acceleration is the same, so it moves at the same speed (if we neglect air resistance). If we look at Newton's second law, F = ma. The force of gravity is F = mg, where m is the mass of the object and g is the acceleration due to gravity.

Equating, we have mg = ma. Therefore, a = g.

If there was no air resistance, a feather would fall at the same speed as an apple.

i think it'll be 7,000

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
