Redshift Z = V_r/c, Where V_r Is the Apparent Recessional $\lt$

question 7

Multiple Choice

Redshift z = v_r/c, where v_r is the apparent recessional velocity, and c is the speed of light.Is it possible to observe a redshift greater than 1.0, or lower than=1.0?

• A) Neither is possible.
• B) Yes, it is possible to measure both.
• C) It is possible to measure z \(\lt\) -1.0, but not z \(\gt\) 1.0.
• D) It is possible to measure z \(\gt\)1.0, but not z \(\lt\) -1.0.
• E) Redshifts greater than 1.0 and less than -1.0 are the only possible redshifts.

Definitions:

Tidal Volume

The volume of air displaced between normal inhalation and exhalation when extra effort is not applied.

Cardiac Output

The volume of blood the heart pumps through the circulatory system in one minute, an important measure of heart function and efficiency.

Stroke Volume

The amount of blood pumped by the left ventricle of the heart in one contraction, indicating the heart's efficiency in pumping.

Myocardial Contractility

The ability of the heart muscle (myocardium) to contract or shorten, which is a key factor in the heart's function to pump blood.
