題目是醬子的
Earth's atmosphere is constsntly bombarded by cosmic ray protons that
originate somewhere in space.If the protons all passed through the
atmpsphere,each square meter of Earth's surface would intercept protons
at the average rate of 1500 protons per second.What would be the electric
current intercepted by the total surface area of the planet?
請問有哪位學長姐會這個題目的嘛???
什麼宇宙大爆炸什麼鬼的...
