Final question: if an object absorbs red and green light outside in the daylight, what color will it look to our eyes?

Blue

Explanation:

Objects absorb and reflect light differently according to their physical characteristics. The color we perceive of an object is the range of the spectrum of light that it does not absorb. We capture that "rejected" light, through the eyes, thanks to its structure.

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
