Miss Rogers taught physics in a New York.Last month she was explaining to one of her classes about sound."Now I have a brother in Los Angeles.If I was calling him on the pgone,and at the same tine you were 75 feet away listening to me across the street,which of you would hear what I said earlier,my brother or you,and for what reason?"
John answered,"Your brother,Miss Rogers,because electricity travels faster than sound waves.""that's very good,"Miss Rogers said.
"I disagree,"said Mary."Your brother would hear you earlier,because when it's eleven o'clock here,it's eight o'clock in Los Angeles."
Rogers老师在纽约教物理.上个月,当她给一个班解释关于声音的问题时,她问:"假如现在我有一个哥哥在洛杉矶.如果我在电话里喊他,同时你在离我75码远的街道对面,那么,你和我的哥哥谁会更早听到我的声音,为什么?”
John 回答道:“你哥哥,Rogers老师,因为电的传播速度比声波快.”“很好."Miss Rogers说.
"我不同意,"Mary说,"你哥哥会先听到是因为我们这里是十一点,而在洛杉矶是八点."
