Answer:
I think the density of the object determines if it floats or sinks
Explanation:
The video camera will record
A ball moving towards the camera, initially faster and then slower.
density = mass /volume
1)mass of rock = 26.0 gram
2)volume of rock = volume of water it has displaced= 25.3-13.12 = 12.18
put the value of mass and volume in first equation and get the density value
