Part B Light waves have some similarities with water and sound waves, but they are not exac

divide the right side by the left side

0.024÷1.2=0.02 for example

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.
