Answer:
B(A)100=B(B), the star A is 100 times fainter than star B.
Explanation:
Brightness of the star is defined by the formula,
Here, L is the luminosity and d is the distance.
For star A, the distance is 10d. The brightness of star A.
For star B, the distance is d. The brightness of star B.
Now according to the question luminosity of two stars is equal.
Therefore,
So, star B is 100 times brighter than star A.
Therefore the star A is 100 times fainter than star B.
Tropic of Cancer, latitude approximately 23°27′ N of the terrestrial Equator. This latitude corresponds to the northernmost declination of the Sun’s ecliptic to the celestial equator. At the summer solstice (in the Northern Hemisphere), around June 21, the Sun attains its greatest declination north and is directly over the Tropic of Cancer. At that time the Sun appears in the constellation Gemini, but much earlier in history, it lay in the constellation Cancer, thereby resulting in the designation Tropic of Cancer. Because of the gradual change in the direction of Earth’s axis of rotation, the Sun will reappear in the constellation of Cancer in approximately 24,000 years.
