The word 'apparent' mean in apparent visual magnitude is, how bright the star appears when viewed from Earth.
What is visual magnitude?
The brightness of a celestial body is determined by eye estimation with or without optical aid or by other instrumentation equivalent to the eye in spectral sensitivity.
Apparent magnitude:
- Apparent magnitude is a measure of how bright the star appears when viewed from Earth.
- It is a measure of the brightness of a star or other astronomical object observed from Earth.
- An object's apparent magnitude depends on its intrinsic luminosity and its distance from Earth.
Hence,
The word 'apparent' mean in apparent visual magnitude is, how bright the star appears when viewed from Earth.

Answer:
(a) Maximum current through resistor is 1.43 A
(b) Maximum charge capacitor receives is 
.
Explanation:
(a)
In an RC (resistor-capacitor) DC circuit, when charging, the current at any time, <em>t</em>, is given by
Here, 
is the maximum current and <em>τ</em> represents time constant which is given by RC (the product of the resistance and capacitance).
The maximum current is given by
<em>V</em> is the emf of the battery and 
is the effective resistance.
In this question, = 10.0 Ω + 25.0 Ω = 35.0 Ω
(b) The maximum charge is given
<em>Q</em> = <em>CV</em>
where <em>C</em> is the capacitance of the capacitor
The answer: 3.00 * 10 ⁸ .
