When Henrietta Leavitt discovered the period-luminosity relationship, she used Cepheid variable stars that were all located in t

he Large Magellanic Cloud (LMC). It was (easier / more difficult ) to compare Cepheids in the LMC rather than those located in the Milky Way Galaxy because they are all ( about the same distance away / located at widely varying distances from Earth ). As a result ( differences in apparent brightness are directly related to differences in intrinsic brightness of these stars / all of these stars have the same Doppler shift / all of these stars have the same proper motion )

This is further explained below.

<h3>What are anthropologists?</h3>

Generally, The study of other primates, such as chimpanzees and apes, teaches anthropologists things about humans that, among other things, help them better comprehend human evolution.

In conclusion, We refer to this all-encompassing strategy for gaining knowledge of the many facets of the human experience as "holism." Anthropologists follow this approach. They do this by using archaeology to go into the past and try to piece together how human societies used to live hundreds or thousands of years ago and what was significant to them.

Did Mr. Roberts cause his own problem by saying he would call back?why or why not?
kotykmax [81]

Answer:

Nope

Explanation:

Step-by-step explanation:

Given: The value of 0.035

Now, as we know 0.035 has three decimal place which mean if we multiply by 1000 then we have the product 35 which is greater than 1 and less than 100, however if we multiply 0.035 by 10000 then the output will be greater than 100, which is invalid.

Lets us use hit and trail method.

0.035 x 1000 = 35 < 100

0.035 x 10000 = 35 > 100

Now lets put the value in expression 0.035 x 10^3
