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?.
Summary
<span>Archimede's Principle of bouyancy states that the bouyant force on an object is equal to the weight of the fluid displaced by that object.<span>The underwater fraction of a substance floating on water is given by that substance's mass density in g/cm3.</span></span>
Answer:
B.
Explanation:
Lamarck's theory basically says that traits that are developed over time can be passed on (Theory of Inheritance of Acquired Characteristics), which is incorrect. Darwin is correct that only traits possessed at birth can be passed on.
Chloroplasts are where photosynthesis occurs, so maybe that's a hint to know which cells have chloroplasts.
Mitochondria. This isn't called the powerhouse of the cell for no reason. lol
It will stay in a persons nervous system for the rest of their life
