<span>One light year is equal to 9.46*10^15 m. The star is 10 light years away, which is the same as 9.46*10^16 meters. The equation that relates brightness to distance and luminosity (in watts) is brightness = Luminosity/(4*pi*distance^2). The sun has a luminosity of 3.8*10^26 watts (NOT 3.8*1026 watts, as indicated in the problem statement). Using the given distance with the actual implied luminosity of the star: Brightness = 2.8*10^26/(4*3.14159*(9.46*10^16)^2) = 2.49 e-9 W/m^2</span>

The statement that shows how the image is a part of the cultural landscape of the area is Both Chinese writing and English writing are used on the front of the building.

The term that best explains the change in the significance of the building is Sequent occupancy.

<h3>How to define cultural landscape?</h3>

Cultural landscape in contemporary geography refers to how cultures would have blended with each other and with the environment at large to become more unique to a particular place.

We can see that the building in the image is part of the cultural landscape of the area because it has both Chinese and English writing to show that it represents a mix of both those cultures.

Sequent occupancy is a term in geography and cultural science that relates to how an area will be influenced by the cultures of those who have lived in the area before, and who now stay in that area.

Sequent occupancy is therefore at play here because the building has been affected by both Chinese people and the culture that built and owned the building which was not Chinese. This meant that the cultural significance of the building changed to be more Chinese overtime.
