what is the question please
Answer: the correct one is E .systems; for example, hurricanes could be prevented from forming by artificial "reefs" of precisely shaped marine platforms
Explanation:
(A) The portion after the semi-colon (for instance, ... platforms) is not a complete sentence.
(B) The portion after the semi-colon (for example, ... forming) is not a complete sentence.
(C) Which ... "reefs" ... prevent forming is unidiomatic; from is needed between prevent and forming. Prevent appears in the present tense, illogically implying that the artificial reefs—which don't yet exist, according to the earlier part of the sentence—already prevent the formation of hurricanes.
(D) The construction such as artificial "reefs" illogically implies that artificial reefs are weather systems. Additionally, the use of can in the present tense (as opposed to could) illogically implies that the artificial reefs—which don't yet exist, according to the earlier part of the sentence—do already exist.
(E) CORRECT. The semicolon is properly used to separate two complete sentences. Could is correctly used to describe a hypothetical consequence.
Recall that
It takes the car about 3.2 s to reduce its speed from 14.6 to 10.8 m/s, since
Next, recall that
Then the car undergoes a displacement of about 41 m, since
Answer:
a) A = [m /s²]
, B = [m / 
]
, b) v = a to + 2B/3
Explanation:
a) to define the units of the constants, we see that the left part has units of acceleration so the right part must also have the same units
A = [m /s²]
B = [m / s²]
B = [m / ]
b) We must use the definition of acceleration
a = dv / dt
dv = adt
We integrate
∫ dv = ∫ (A + B 
) dt
v = a t + B 2/3
We evaluate between:
the lower limit t = 0 v = o and the upper limit t = to v = v
v = a to + 2B/3
c) Let's use the definition of speed
v = dx / dt
dx = v dt
∫ dx = ∫ (a t + 2B/3 ) dt
x = a t²/2 + 2b/3 2/5 
For the interval t = 0 and t = to, we evaluate the integral
x = A/2 t₀² + 4B/15 √t₀⁵
