What does a red shift indicate about a galaxy?
Ad libitum [116K]
The only cause we know of that could shift the spectrum of a source toward longer wavelengths isthe source moving away from us. That's how we interpret the red shift when we see it, and that's where the whole idea of the expanding universe comes from. But ... just like gravity and the Earth going around the sun ... it can't be proved, so it's "only a theory".

Fill in the blanks:<br> 87 pg = [? ]x10^[?]g
jeyben [28]

87 picograms are equivalent to 8.7\times 10^{-11} grams.

This is a unit problem, in which a <em>derived</em> unit must translated into a <em>fundamental</em> unit. A picogram is a equivalent to <em>a trillionth</em> of a gram, which is the fundamental SI <em>mass</em> unit. Mathematically speaking, we have the following equivalence:

1\,pg = 1\times 10^{-12}\,g

Now we proceed to find the equivalent value for this case:

87\,pg

87\times 10^{-12}\,g

8.7\times 10^{-11}\,g

87 picograms are equivalent to 8.7\times 10^{-11} grams.
