Answer:Heat is kinetic energy the higher the temperature of a substance, the faster and farther its molecules move. For example, as heat transfers into the ice, the ice molecules move faster and eventually the ice melts When those molecules slow down, their kinetic energy decreases
Hope this helps! :)
When the metal case of a piece of equipment is connected to ground through a ground wire, any fault current is conducted by the wire, rather than by someone who may touch the case.
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
