Answer:
Stars that have lower apparent magnitudes have more brightness.
Explanation:
Greek astronomer Hipparchus devised a system of arranging the luminosity of stars with their apparent magnitude. The brightest stars were in the first magnitude class, and the dimmer stars were in the latter magnitude classes.
Later in the 19th century technology had developed to accurately measure a star's brightness. It was established that a factor of exactly 100 times in intensity was due to difference of 5 magnitudes.

A parallel plate capacitor consists of two large plane parallel conducting metal plates separated by a small distance. The second plate acts as a neighbouring conductor due to which the potential of first plate is reduced, keeping its size same ;due to which the capacitance increases.
Answer:
Being a plane mirror the Image is formed 3 metres beyond the mirror . So total distance is 3+3 = 6metres
