The answer is C, because there are only so many elements therefor you can have only so many compounds.
Answer:
a nightstand on a lamp table
Explanation:
<span>(A)
s{ t } = (¼)t² + 2t + 1 ... differentiate to get velocity versus time
v{ t } = (½)t + 2 ... linearly increases with time
(1)
Vavɢ{ a→b } = [ v{ b } + v{ a } ] ⁄ 2
Vavɢ{ 1→3 } = [ v{ 3 } + v{1 } ] ⁄ 2
Vavɢ{ 1→3 } = [ (½)(3) + 2 + (½)(1) + 2 ] ⁄ 2
Vavɢ{ 1→3 } = 3 m/sec
(II) and (III) are done the same way.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~...
(B)
v{ t } = (½)t + 2
v{1 } = (½)(1) + 2
v{1 } = 2.5 m/sec</span>
I believe it is D, although you may should learn about all four of these laws.
