What is the flaw with using apparent brightness rather than absolute brightness to determine the brightness of a star?
Apparent brightness does not use the star's color or temperature.
Apparent brightness does not take into account the distance of the star from Earth
Apparent brightness is only theoretical, its value cannot be directly measured with equipment
Apparent brightness is only on a comparative scale that determines how bright a star looks from a theoretical distance of 10 parsecs
from Earth.

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
