题目是酱子的
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?
请问有哪位学长姐会这个题目的嘛???
什麽宇宙大爆炸什麽鬼的...
看都看不懂...
