Suppose a greenhouse is to be constructed to keep plants warm in the winter. which material should be used for the windows of the greenhouse? material (a, b, c, or d) should be used because it will a. let the most solar radiation into the greenhouse. b. absorb radiation emitted by the sun while letting through most radiation from the interior of the greenhouse. c. absorb the most solar radiation. d. absorb radiation from the interior of the greenhouse while letting through most radiation from the sun.

the answers, material D meets the requested characteristics

Explanation:

The objective of an insulating material for the house, must allow solar radiation to enter, so that the plants can perform photosynthesis and must prevent radiation from inside the house from being lost.

Therefore the material must meet two conditions be transparent to sunlight and be absorbed from the radiation coming from the house; this is to leave for visible light and absorb infrared radiation

Reviewing the answers, material D meets the requested characteristics

real, smaller and upside-down.   so the answer should be b.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
