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,

Answer:
c) current
Explanation:
Ohm's law states that the current I flowing through a conductor of resistance R is directly proportional to the voltage or potential difference V applied across its terminals provided that the temperature and other necessary conditions remain constant.
Mathematically this law can be written as follows;
When we make R the subject of formula from equation (1), we get the following;
Before 7 after 9. A pH smaller than 7 indicates acidity with 0 being completely acidic. A pH greater than 7 shows alkalinity with 14 being completely alkaline. 7 is neutral. Since NaOH is alkaline, adding it to a neutral substance would increase the pH and it would increase from 7 to 9.
Chemical energy is the energy released or absorbed in a chemical reaction during the decomposition or formation of compounds
That's the definition but what was d? maybe I can help narrow it down
