The reflectance curve for a white piece of paper would reflect group of answer choices
a) mostly short wavelengths, a moderate amount of medium wavelengths, and a little of the long wavelengths
b) mostly long wavelengths, a small amount of medium wavelengths, and a little of the short wavelengths
c) a little of short wavelengths, a large amount of medium wavelengths, and a little of the long wavelengths
d) long, medium and short wavelengths equally

D)

Explanation:

The reflectance curve for a white piece of paper would reflect Long, medium and short wavelengths equally.

white piece paper serves as perfectly reflective surfaces and reflects all the incident radiations without any absorbtion or transmission. Hence a white piece of paper would reflect Long, medium and short wavelengths equally.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

it has to be b, about 97 percent.
