answer
64 is C (c) 1-Bromo-3-methylbutane
63 is D
i is secondary ii is primary
<span>The initial momentum is 5 kg m/s and the final momentum is 10 kg m/s
'cause P = m*v, when we increase either m or v, P also increases by the same expression,
P = 5 * 2 = 10
So, option D is your answer!!
Hope this helps!

Answer:
40 J
Explanation:
= 4 C
= 2 C
= 20 J
The potential energy is directly proportional to the charge of the particle


The potential energy expected is 40 J
<h2>Answer:</h2>
