What else can I help you with?
If all the main sequence stars of a star cluster are typically only one hundredth as bright as their main sequence counterparts in the Hyades Cluster than the cluster's distance?
can be estimated by comparing their apparent magnitudes. Since brightness decreases with the square of the distance from an observer, a star cluster with main sequence stars one hundredth as bright as the Hyades Cluster would be approximately ten times further away from Earth than the Hyades Cluster.
Why are pulsating variable stars useful for finding distances to globular clusters?
It really depends on the type of star, but for certain star types, there is a relationship between the period and the absolute brightness, so if the period is observed, the absolute brightness can be deduced. Yes. It seems like this question is about the Cepheid variables.
What affects absolute brightness?
Brightness corresponds to amplitude of waves. Greater amplitude means greater brightness (so lower amplitude means less brightness).
Is the Virgo cluster a globular cluster?
No, a globular cluster is a group of stars that are part of a galaxy. The Virgo cluster is much bigger. It is a large nearby group of galaxies.
What is a spherical cluster of stars?

How do you use brightness in a sentence?

Should the instrument cluster on your 2001 beetle be lit up?
Sure, as long as the brightness control isn't turned off.
How do you fix dim lights on a 1989 Ford Probe cluster?
Turn the brightness control up. Could be the reset button for the odometer or another switch.

Where is reset button on clk Mercedes?
depends on the year if you have the trip computer on the dials display then its normally on the far left hand side of the instrument cluster just below 2 other buttons, up and down for the brightness of the cluster etc. mines a 2001 and is in this place...

First be sure the dash light brightness control switch is not turned off then check the fuse.
