A sample made of a lot of radioactive nuclei started to decay immediately after it was generated. -
Ssongoku posted the thread Correct statement about random process of radioactive decay in Introductory Physics Homework Help.The correct answer is (C) but I don't understand why (B) is wrong. Isn't (B) also the meaning of random process? I though (B) and (C)...

I believe @haruspex nailed it. A charge induce on the ground by a cloud is called induction. It's the term used in that situation.

Also known as induction.

I would interpret the diagram this way: Both clouds are discharging electrons (negative charge) to the ground. This is evidence that...

Ssongoku replied to the thread Which one is correct statement regarding lightning?.For this case, is this also called induction?

-
Ssongoku replied to the thread Which one is correct statement regarding lightning?.If that is the case, there is discharging between the clouds so can I say there is induction between clouds? Thanks

Ssongoku posted the thread Which one is correct statement regarding lightning? in Introductory Physics Homework Help.My answer is (B) but the correct answer is (D). I don't understand why there is induction between clouds and ground. I thought there...
