Answer:
Luminosity is an intrinsic(natural) measurable property of a star independent of distance. The concept of magnitude, on the other hand, incorporates distance. The apparent magnitude is a measure of the diminishing(decrease) flux of light as a result of distance according to the inverse-square law.
Answer:
The correct answer is - 0 m/s.
Explanation:
In this position-time graph or distance-time graph, there are three different part that shows three different velocities one in increasing as it moves from a lower position in relative to time and one is stationary and the third is decreasing.
'Straight lines' on a distance-time graph suggest that the movement of the object is constant. During 'Part B' of the journey the object travels 0m in 3s. It is stationary for 3 seconds so the velocity will be zero as well.
Hydrogen is abundant in the sun.
