((50 points - brainliest for best answer)) what makes apparent magnitude different from absolute brightness?include an example in your response.

The main difference between absolute and apparent magnitude is that apparent magnitude measures the observed brightness of an object from any point, whereas absolute magnitude calculates the brightness of the object as seen from a standard distance away from the object.

Example: Absolute Brightness: How bright a star appears at a certain distance.Apparent Brightness: The brightness of a star as seen from Earth.

Apparent brightness is the optical illusion where the source of light is different while absolute brightness of a star is the aura of the star .

i don,t know so just answer mine

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
