Determining the composition of stars is one way that light emission has been used to determine the chemical composition of an object. light emission is still used today by researchers. it is harnessed in instrumentation such as flame atomic absorption spectroscopy. provide an explanation of how this instrument works as if you are describing it to your non-science roommate. also, provide at least two uses of such an instrument.

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

distance, luminosity, brightness, radius, chemical composition, and temperature

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
