That's the first thing that can be observed about a star. You can't immediately figure out a star's real (absolute) brightness; this requires a more detailed analysis, and for far-away stars it may be difficult to get this information with a reasonable accuracy.

What information is needed to plot a star on the H-R diagram?

To plot a star on the H-R diagram, you need the star's luminosity (or absolute magnitude) and its surface temperature (or spectral type). These two properties allow you to place the star accurately on the diagram based on its position relative to other stars.


How complex numbers are used in determining gain of a system?

Since complex numbers can be expressed as magnitude and angle, a plot of a system's response can be approximated with a Bode plot (see related link). The gain is the magnitude, and the phase shift is the angle change of the system.

What is another name for a plot of surface temperatures of stars against their absolute magnitude?

This plot is commonly referred to as a Hertzsprung-Russell (H-R) diagram, named after the astronomers Ejnar Hertzsprung and Henry Norris Russell who independently developed it in the early 20th century.


How does uncompetitive inhibition affect the Michaelis-Menten plot?

Uncompetitive inhibition affects the Michaelis-Menten plot by decreasing both the maximum reaction rate (Vmax) and the apparent Michaelis constant (Km). This results in a parallel shift of the plot to the right along the x-axis.
