Answer:

Explanation:
We need only to apply the definition of acceleration, which is:

In our case the final velocity is
, the initial velocity is
since it departs from rest, the final time is
and the initial time we are considering is 
So for our values we have:

Answer:
Explanation: This is done using the equation:

Because the Radius is a know value. We have the following.

Which is:
4188.7902 mm
A fish pushes water backwards in order to move forward is a good example of Newton's 3rd Law.
A conservative force is a force that when work is done against this force the work done does not depend on the path taken only the initial and final position.
That would make a cation. If it gained one instead, then it would make an anion.
