Answer: Bob's private key
Explanation:
Since Bob is sending Alice the message, it simply implies he must have encrypted it with his key that Alice can be able to use to decrypt the message.
Answer:
Part A: Q = 0.075C
Part B: E = 187.5J
Part C: I = 50A
Part D: ΔQ 1.53C
Explanation:
Part A
Q = C×V
Given
C = 15μF = 15×10‐⁶ F, V = 5kV = 5000V
Q = 15×10‐⁶× 5000 = 0.075C
Part B
Energy = E = 1/2 ×CV² = 1/2 × 15×10‐⁶ × 5000² = 187.5J
Part C
Given R = 100Ω
V = IR, I = V/R = 5000/100 = 50A
Part D
I = ΔQ/Δt
Given Δt= 90ms = 90×10-³s, I = 17A
ΔQ = I × Δt = 17×90×10-³ = 1.53 C
C dependent variable because dependent means relying on something else
