My first football   小题1:  ( compete) was in Nagoya, Japan several years ago. Last year our team went to Seattle, Washington in the USA. We   小题2:  (win) second place.   小题3:  (personal), I think the team that got first place cheated, because they had developed a new type of program just    小题4:  the match began. So we need to encourage our programmer to improve our intelligence too. We are  小题5:  (determine) to create an even  小题6:  (good) system. In a way our programmer is like our coach. She programs us with all    小题7:  possible moves she has seen while   小题8:  (watch) human games. Then she prepares reliable moves to use if a new situation arises. In this way I can make up new moves using my “artificial intelligence”. I would really like to play against a human team, for I have been programmed to act just like them. After all,    小题9:  the help of my electronic brain that never forgets anything, using my intelligence is   小题10:  I’m all about!

在如图甲、乙、丙中，除导体棒ab可动外，其余部分均固定不动，甲图中的电容器C原来不带电．设导体棒、导轨和直流电源的电阻均可忽略，导体棒和导轨间的摩擦也不计，图中装置均在水平面面内，且都处于方向垂直水平面（即纸面）向下的匀强磁场中，导轨足够长．现给导体棒ab一个向右的初速度v₀，在甲、乙、丙三种情形下导体棒ab的最终运动状态是（　　）

A．三种情形下导体棒ab最终都做匀速运动

B．甲、丙中，ab棒最终将以不同速度做匀速运动；乙中，ab棒最终静止

C．甲、丙中，ab棒最终将以相同速度做匀速运动；乙中，ab棒最终静止

D．三种情形下导体棒ab最终都做静止
