Can anyone help me please I need this in a few mins When measuring the brightness of a star, what is a limitation of using apparent magnitude rather than absolute brightness?

Apparent magnitude does not use the star's color or temperature.

Apparent magnitude is only theoretical, thus its value cannot be directly measured with equipment.

Apparent magnitude does not take into account the fact that not all stars are the same distance from Earth.

Apparent magnitude is only on a comparative scale that determines how bright a star looks from a theoretical distance of 32 light-years from Earth.

D. Apparent magnitude is only on a comparative scale that determines how bright a star looks from a theoretical distance of 32 light-years from Earth.

i dont know it at allnow im just getting points at this pint

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .

no u
