They have Different atomic masses so its A.
Answer:
Once used as a energy source they cannot be charged/used again.
Explanation:
Answer: it’s 3 seconds
The power of the pulse is 40 Watts
See below
Total current will be 18 v/ 8 ohms + 18v / 24 ohms = 3 amps
Equivalent resistance = 1 / (1/8 + 1/24) = 6 Ω
