On 23rd December, 2013, Michael Schumacher — the famous Formula-One race car driver — received serious brain injuries after hitting his head on a rock while downhill skiing with his son. The accident happened during a family holiday in the French Alps. Although he was wearing a helmet, which broke apart on impact, the F1 celebrity was moving at speeds of up to 62 mph and skiing outside the off-piste safety demarcations (滑雪场地外的安全区). Doctors reported that he would have died on impact if he hadn’t been wearing a helmet. He has been in a coma (昏迷) since arriving at a nearby hospital where he was airlifted to from the site of the accident.

Michael Schumacher grew up in frugal (简朴的) conditions and started what would become his remarkable professional career when his working class father — a bricklayer — built him a from where he started participating in competitions.

（B）处于n＝3激发态的一群氢原子，自发跃迁时能发出3种不同频率的光 （C）放射性元素发生一次β衰变，核电荷数增加1

（D） 92U的半衰期约为7亿年，随着地球环境的不断变化，半衰期可能变短 （2）用能量为E0的光子照射基态氢原子，刚好可使该原子中的电子成为自由电子，这一

能量E0称为氢的电离能．现用一频率为ν的光子从基态氢原子中击出一电子（电子质量为m），该电子在远离核以后速度的大小为 ▲ ，其德布罗意波长为 ▲ ．（普朗克常量为h）

（3）静止的锂核6106m/s的中子，发生核反应后产生了两个新粒子，3Li俘获一个速度为8×

其中一个粒子为氦核2He，它的速度大小是3.5×10 m/s，方向与反应前的中子速度方向相同，试写出核反应方程，并求反应后产生的另一个粒子的速度大小．

四、计算题：本题共3小题，共计47分．解答时请写出必要的文字说明、方程式和重要的演算步骤．只写出最后答案的不能得分．有数值的题，答案中必须明确写出数值和单位． 13．（15分）如图所示，光滑导轨MN和PQ固定在同一水平面上，两导轨间距为L，两端分别接有
