It's highly reactive and contains only one valence electron
Answer: B) 30 km/h
Explanation:
The speed of Ben and Jerry on their way to the store is given by
where
d is the distance they covered
t is the time they took
From the graph, we see that Ben and Jerry travelled for a distance of d=60 km in a time of t=2 h, so their speed is
Answer:
√2
Explanation:
If the final kinetic energy is 2 times the initial kinetic energy:
KE = 2 KE₀
½ mv² = 2 (½ mv₀²)
v² = 2 v₀²
v = √2 v₀
Therefore, the ratio of the final momentum to the initial momentum is:
p / p₀
mv / (mv₀)
v / v₀
√2
A conductor allows electricity to flow through it.
