Question

name hr - diagram practice
hr - diagrams are graphs that allow scientists to plot stars based on temperature and luminosity. answer the following questions about graphing using the paper copy of the hr - diagram you just received as the graph.

1. what are the two variables on the hr - diagram? (3 pts)
2. the luminosity of a star depends on which variable? (2pts)
3. what is the title of this graph? (2 pts)
4. what is the independent variable of this graph? (2 pts)
5. what is the dependent variable of this graph? (2 pts)
6. what is the scale used on the y - axis? (2 pts)

what is the interval on the y - axis? (2 pts)

Explanation:

1. HR - Diagrams plot stars based on temperature and luminosity, so these are the two variables.
2. The luminosity of a star depends on its surface area and temperature.
3. The title given in the text is "HR - Diagram Practice".
4. In an HR - Diagram, temperature is typically the independent variable.
5. Luminosity is the dependent variable as it depends on other factors like temperature and size of the star.
6. The y - axis of an HR - Diagram usually represents luminosity. The interval would depend on the specific scale used in the given diagram (not provided here).

Answer:

1. Temperature and luminosity
2. Surface area and temperature
3. HR - Diagram Practice
4. Temperature
5. Luminosity
6. Luminosity (interval not determinable from given info)
