When the continental drift occured, it moved all the land on earth around, therefore changing climates. If fossils of animals are found on a certain continent that doesn't support that species, it proves the drift happened because the climate used to be suitable for them, but now is not.
C. Because protons are the identity of the atom.
False, agility is more about how fast you are
The angular momentum is defined as,

Acording to this text we know for conservation of angular momentum that

Where
is initial momentum
is the final momentum
How there is a difference between the stick mass and the bug mass, we define that
Mass of the bug= m
Mass of the stick=10m
At the point 0 we have that,

Where l is the lenght of the stick which is also the perpendicular distance of the bug's velocity
vector from the point of reference (O), and ve is the velocity
At the end with the collition we have

Substituting




Applying conservative energy equation we have


Replacing the values and solving

Substituting
l=\frac{13}{0.54(9.8)}
