     Mr and Mrs Wilson and their children were going to begin their holiday one day, and they must be at

 the airport at eleven forty in the morning. "It will take us half an hour to get there in the car, "Mr Wisson

 said. "So we must get there before eleven o'clock. Don't be late."

     At ten minutes to eleven, they were busy doing things, but Mrs Wilson didn't. She was sitting quietly

 in a chair in the garden, enjoying the sun.

     Her husband and children were very surprised. Why wasn't she busy too? Mrs Wilson answered,

 "Well, before I went to bed last night, I moved all our clocks and watches ahead (提前) twenty minutes.

 So now we can go to the airport quietly without worrying about being late."

( ) 1. The Wilson family had to be ready by 11:00, because they had to go to a town.

(     ) 2. At ten fifty, Mr Wilson and the children were all very busy.

如图所示,在匀强磁场中竖直放置两条足够长的平行金属导轨,磁场方向与导轨所在平面垂直,磁感应强度大小为B0.导轨上端连接一阻值为R的电阻和开关K,导轨电阻不计,两金属棒a和b的电阻都为R,质量分别为ma="0.02" kg和mb="0.01" kg,它们与导轨接触良好,并可沿导轨无摩擦地运动.若将b棒固定,断开开关K,将一竖直向上的恒力作用于a,稳定时a棒以v=10  m/s的速度向上匀速运动,此时再释放b棒,b棒恰能保持静止,取g=10  m/s2,求:

(1)若将a棒固定,开关K闭合,让b棒从静止开始自由下滑,求b棒滑行的最大速度;

(2)若将a、b棒都固定,断开开关K,使匀强磁场的磁感应强度在0.1 s内从B0随时间均匀增大到2B0时,a棒所受到的安培力恰好等于它的重力,求两棒间的距离.
