    题目列表(包括答案和解析)

    在物理学中，磁场的强弱用磁感应强度（用字母B表示，国际单位是特斯拉，符号是T）来表示，磁感线越密的地方，磁场越强，磁感应强度B越大.

    （1）在图20中，甲为某磁极附近磁感线的方向和分布的示意图，由图可知，该磁极为 ▲ 极，若在l处放置一个小磁针，当小磁针静止时，其指向应是图乙中的  ▲   .
    （2）磁敏电阻阻值的大小随磁场的强弱变化而变，图丁是某磁敏电阻R的阻值随磁感应强度B变化的图象，据图线可知，磁敏电阻的阻值随磁感应强度B的增大而▲ ．图线没有过坐标原点，说明  ▲  .
    （3）王强设计了一个可以测量该磁敏电阻R的电路如图丙所示，（其中磁敏电阻所处的磁场未画出）．将该磁敏电阻R放置在磁场中的位置某处，测出电阻后，利用R—B特性曲线可以读出相应的磁感应强度.
    ①在图甲磁场中1处，测得的数据如图20表中所示，则该磁敏电阻的测量值为 ▲ Ω. 
    ②根据该磁敏电阻的R-B特性曲线可知，1处的磁感应强度为   ▲    T.
    ③在实验过程中，仅将磁敏电阻从1处移至2处，其它条件不变，那么电流表的示数
    ▲   （填“增大”、“减小”或“不变”）.
    ④依据上述方法获得的磁感应强度B的测量值与该点实际值存在不小的误差，为尽可能准确反映空间某点磁场的强弱，你认为在选择磁敏电阻时应注意什么问题？

    2005年5月，西南科技大学电子商务系高材生、年轻黑客彭博被公诉至海淀法院。起因是彭博多次盗用14位中国建设银行信用卡用户1.9万余元资金，购买游戏卡及神州行卡，并同朋友一起在北京珠峰伟业“网络热游戏卡专卖店”内进行网上销售。这种行为无异于抢劫银行，将给网上银行系统造成毁灭性打击。这一事实说明青年学生（    ）
    A．要用科学文化知识武装头脑B．要注意自身的思想道德修养
    C．思想道德修养比知识文化修养更重要D．要与资本主义腐朽思想划清界限
