Gold is denser than silver. A 1 cm cube of gold has more mass than a 1 cm cube of silver. However, if we could see the atoms of gold and silver, we would see that they are exactly the same size. A 1 cm cube of gold has the same number of atoms as a 1 cm cube of silver. What does this tell us about the atoms of gold and silver.

12am gold

Explanation:

i think the answer is a, hope this : )

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.
