Chapter 10 Questions and Answers 2024 The star Bernard's Star has an apparent magnitude of 9.5 and the star Lelande 21185 has an apparent magnitude of 7.5. Which one is brighter? By how many times? Lelande 21185 is the brighter star as the more negative the magnitude is, the brighter the object is. Subtract the two magnitudes and take the absolute value to get a positive answer. Then use that answer as the power on 2.512. |9.5-(+7.5)| =2| =2| 2.5 ^2 = 6.25 Therefore Lelande 21185 is about ...

A curious fact about the structure of the planet Jupiter, compared to that of Earth, is that it has - much greater mass but much lower average density. A good example of a positive feedback effect in global warming is that melting sea ice causes a decrease in the Earth's albedo, meaning we absorb more sunlight than ever. T/F - T A main sequence star of mass 3 M☉has a luminosity of approximately 50 L☉. How long is the Main Sequence phase for such a star? - 6 x 10^8 years A planet can o...

GIZMOS Student Exploration; Big Bang Theory | Hubble’s Law 2023. Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Standing by the side of a lonely highway at night, you see two motorcycle headlights, one in each direction. The headlight on your left appears brighter than the one on your right. 1. If the headlights are equally bright, which motorcycle is closer? The one on the left side Explain: If it is brighter than that means its going to be closer because the light particle...

Astronomy 1010 Final HW One of the most important earlier steps in understanding stars was to group them into classes called spectral types that could offer clues as to why they are different from one another. Shown here are spectra of some main-sequence stars. Before stars were very well understood, they were classified into an order that was based on the relative strength of hydrogen absorption lines, marked by arrows the image shown. Look at the spectra for stars of different spectral ...
