An astronomer has been observing two Cepheid variable stars over the course of a month. Both variable stars have the exact same

period of pulsation. Star A is twice as bright as Star B. Which of the following statements most accurately reflects the relationship between the astronomer (on Earth) and both Cepheid variable stars? Stars A and B have the same luminosity, but Star A is closer to Earth than Star B.Stars A and B have the same luminosity, but Star B is closer to Earth than Star A.Stars A and B are both the same distance from Earth, but the luminosity of Star A is greater than Star B

Answer:

The luminosity of both the stars is same star A is closer to the planet Earth as compared to star B.

Explanation:

From the mentioned case we can infer that the most accurate relation between the stars and the astronomer on earth observing for over a period is that the luminosity of the stars is same.

The more drawn out the pulsation time frame, the more brilliant the star. The period-luminosity connection for old style Cepheid was found in 1908 by Henrietta Swan Leavitt in an examination of thousands of different stars in the Magellanic Clouds.

Spatial concepts help to explain the distribution of phenomena on Earth.

<h3>What is Spatial concepts in geography?</h3>

Spatial concepts provide a language for explaining the configuration of individuals, places, and environments. Arrangements can be represented in terms of proximity, distance, scale, clustering, distribution, etc.

Geographic concepts permit the exploration of relationships and connections between individuals and both natural and cultural environments. They include a spatial component. They furnish a framework that geographers utilize to interpret and symbolize information about the world.

Geography's unique method of understanding the world exists through spatial patterns and associations. A geographer visualizes and analyses spatial associations between objects i.e. they utilize notions such as location, distance, direction, shape, and pattern.

Spatial distribution in statistics exists in the arrangement of a phenomenon across the Earth's surface and a graphical display of such an interpretation exists as an essential tool in geographical and environmental statistics.

Hence, Spatial concepts help to explain the distribution of phenomena on Earth.
