The brightness of a star.
-
Magnitude
-
Fusion
Correct Answer
A. MagnitudeExplanation
The brightness of a star is measured using the concept of magnitude. Magnitude is a scale that astronomers use to quantify the brightness of celestial objects, including stars. The magnitude scale is logarithmic, meaning that each whole number increase or decrease represents a factor of 2.5 in brightness. A lower magnitude value indicates a brighter star, while a higher magnitude value indicates a dimmer star. Therefore, the term "magnitude" is the correct answer to describe the measurement of a star's brightness.Rate this question:

____________ are powerful magnetic fields that block the flow of gases from beneath the photosphere.
Correct Answer
SunspotsExplanation
Sunspots are powerful magnetic fields that block the flow of gases from beneath the photosphere. These dark spots on the surface of the Sun are cooler than their surroundings and are associated with intense magnetic activity. The magnetic fields in sunspots are so strong that they can inhibit the convective flow of gases, causing a decrease in temperature and brightness in those regions. This phenomenon is known as the Wilson effect and is responsible for the distinctive appearance of sunspots on the Sun's surface.Rate this question:
