Consider this equation: Kinetic Energy = mv2Which of those variables is changing as the skater moves up and down the track?

The changing variables are: v and KE

Explanation:

Given

Required: What changes?

From the formula above:

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

c-reactive protein (crp) is an acute phase protein belonging to pentraxin family of proteins, whose levels increases 1000-fold or more in concentration in blood during the occurrence of an injury, inflammation or tissue death.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
