Maybe, but she hasn't proved it yet. As another example, somebody may bring a jar of gas to your laboratory, and you test the gas in the jar and you find nitrogen atoms, oxygen atoms, argon atoms, and krypton atoms, and there isn't a single compound in it. The gas in the jar is a MIXTURE of gases . . . a mixture that we call "Air".

The weight of the water displaced is the same as the total weight of the
wood block. The fact that 1/3 of the block is above the water level
does not matter if you just weigh the total block of wood , then the
weight of the total block of wood = the weight of the water displaced by
the block of wood. If you want to find density of the block of wood
that is a different question - then you need the volume of the block of
wood and the information about one- third of the total weight . I hope this helped</span>
The skier’s change in velocity is 8.33.../8.4 m/s.
21/63= 0.33...
0.33...x 25 s = 8.33.../8.4 m/s
There was no evidence for people to prove that the theory was incorrect
