More energy is being used in the movement
20 electrons and 2 valence electrons
Answer:
A) It requires extremely high pressure.
Explanation:
The reasons why we haven't been able to harness power from fusion is that its energy requirements are unbelievably, terribly high.
The answer is Prove a hypothesis
Answer:
-4,651.42N
Explanation:
Since we are not asked what to find, we can calculate the force applied by the track as shown;
F = ma
F = m(v-u)/t
Substitute the given value
F = 4400(7.6-52)/42
F = 4400(-44.4)/42
F = -4,651.43N
Hence the required force is -4,651.42N
