The answer would be C. Lightning occurs when the negative charges from clouds attract towards the positive charges on the ground. These two charges attract and cause the spark of lightning. Hope this helps.
Yes Kepler did propose the modern model of the solar system.
I honestly have no idea what the answer is but I'll just give it a go: It will conduct electricity irregularly
1) Equivalent resistance, 1/R = 1/15 + 1/40 + 1/60 = 8+3+2 /120 = 13/120
R = 120/13 = 9.23
2) Current, I = V/R = 115/9.23 = 12.45 A
