Answer:
B) It does not deflect at all
Explanation:
Since both half shells contain opposite charges, the two shells become electrically neutral when they are brought together and the electroscope discharges. On separating the two half shells again, the needle does not deflect because the half shells have now lost their charges to become neutral.

<span>The SLOPE of a position-time graph represents an object’s SPEED.
It's not possible to tell the object's velocity from the graph, because

Answer:
5.7 s
Explanation:
Given:
a = 3.0 m/s²
v₀ = 8.0 m/s
v = 25.0 m/s
Find: t
v = at + v₀
25.0 m/s = (3.0 m/s²) t + 8.0 m/s
t ≈ 5.7 s
