Speed is the rate of change in distance.

The iceberg has weight Wi = Mig and the buoyant force is equal to the weight of the displaced water, Ww = Mwg. Furthermore, since the iceberg is floating, its weight exactly balances the buoyant force:
Ww = Wi
Mwg = Mig
VwRhowg = ViRhoig
Vw = Rhoi/Rhow Vi
So, the fraction of ice underwater, Vw/Vi, is given by the ratio of densities Rhoi/Rhow=0.87. Over 87% of an iceberg's volume (and mass) is underwater. As you can see, the convenient definition of the gram gives us a quick way to see how much of a floating substance lies below the surface of fresh water: the fraction is equal to that substance's mass density in g/cm?.

What are the answer cheseis
The example given explains neuroplasticity.
Neuroplasticity, is also referred to as brain plasticity and this occurs when there's a change in the nervous system as a result of a response to a particular stimuli.
In this case, the neural networks that are in the brain will change and the changes can bring about systematic adjustments in the body.

I don't know the answer options, but it would probably either be phase of matter or physical change.
