Answer:
The changing variables are: v and KE
Explanation:
Given
![KE = \frac{1}{2}mv^2](https://tex.z-dn.net/?f=KE%20%3D%20%5Cfrac%7B1%7D%7B2%7Dmv%5E2)
Required: What changes?
From the formula above:
![KE=Kinetic\ Energy](https://tex.z-dn.net/?f=KE%3DKinetic%5C%20Energy)
![m = Mass](https://tex.z-dn.net/?f=m%20%3D%20Mass)
![v = Velocity](https://tex.z-dn.net/?f=v%20%3D%20Velocity)
m: The mass of the skater is constant.
v: Moving up and down the track may change the velocity of the skater.
KE: When velocity changes, the kinetic energy also changes
So:
The changing variables are: v and KE
Answer:
Eukaryotes are organisms whose cells have a nucleus enclosed within membranes, unlike prokaryotes, which have no membrane-bound organelles.
Explanation:
Answer:
A nucleotide is one of the structural components, or building blocks, of DNA and RNA. A nucleotide consists of a base (one of four chemicals: adenine, thymine, guanine, and cytosine) plus a molecule of sugar and one of phosphoric acid.
