During the day, the sun appears yellow in the sky. but as sunset approaches, the sun appears to change color. this can be explained by the a) absorption of yellow wavelengths on earth and the reflection of red into the atmosphere. b) change in water color on earth that is then reflected into the sky as red and orange hues. c) scattering of light due to particulates in the atmosphere sending mostly red and orange wavelengths back to our eyes. d) refraction of white light into only two color bands, red and orange and the reflection of those colors into the atmosphere. submit

The earth remains in orbit around the sun due to the force of gravity. how does the force of gravity exerted by the sun on the earth compare to the force of gravity exerted by the earth on the sun?

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
