How does light from stars indicate the universe is expanding?

Mathematics
1 answer:
blondinia [14]3 years ago
4 0

Answer:

So, if a star is moving towards Earth, it appears to emit light that is shorter in wavelength compared to a source of light that isn't moving. ... In contrast, the light from a star moving away from us seems to shift towards longer wavelengths. As this is towards the red end of the spectrum, astronomers call it redshift.

hope this helps

plz mark me brainliest:)

Consider the numbers 4/15 and 3/10 (a) Compare the numbers. (B) find a fraction between the two given numbers
valentinak56 [21]
As a decimal 4/15 = 0.2666667
As a decimal 3/10 = 0.3 [talk about close]
3/10 is bigger.

You could take an average to find something between 4/15 and 3/10
1/2(4/15 + 2/10)
1/2(8/30 + 6/30)
1/2(14/30)
1/2(7/15)
7/30 is between the two given numbers..

The cost of a stove to a store owner was $500, and she sold the stove for $1080. What was her percent of profit based on cost?
Juliette [100K]

Answer:

116%

Step-by-step explanation:

Cost Price (C. P.) = $500

Selling Price (S. P.) = $1080

Profit = SP - CP = $1080 - $500 = $580

Profit percent

=  \frac{Profit}{CP}  \times 100 \\  \\  =  \frac{580}{500}  \times 100 \\  \\  =  \frac{580}{5}  \\  \\  = 116 \%
