2(或 3 与 4,或 5 与 6)中 F与 V物 的关系及相关条件,可得出的初步结论是:_______________________________________________________;③进一步分析表一中的数据,发现浸没的物体沉入水底后,存在 相同的现象。若用其它物体进一步实验,请在表二中填入拟进行实验的数据。________________26. 小王在“用电流表、电压表测电阻”的实验中,元件均完好,电源电压为 2 伏的整数倍,滑动6变阻器上标有“20Ω 2A”字样。他正确连接电路,实验步骤正确,闭合电键后,电流表的示数如图 14(a)所示;当把滑动变阻器的滑片 P 恰好移到中点时,电压表示数如图 14(b)所示;小王继续移动滑片 P,在确保安全的情况下,又测得电路中的最大电流为 0.42 安。根据以上信息,小张经思考后认为,小王所用的电源电压为 6 伏,请你通过计算说明,小张的判断是正确的。_____________请将下表填写完整。___________________(计算电阻时,精确到 0.1 欧)7参考答案1、选择题1 2 3 4 5 6 7 8A B D C D B B C2、填空题9. 1.5;串联;22010.千克每立方米;质量为 0.8×103千克;煤油11.
