12、的压力。10.在水平高速公路上做匀速直线运动的汽车，此时汽车的牵引力等于（选填“大于”、“小于”或“等于”）汽车所受到的阻力；行李架上的物体以汽车为参照物，它是静止的，以地面为参照物，它是运动的。11.晶体在熔化的过程中需要不断从外界吸收热量，温度保持不变；钨的熔点是3410，它的凝固点是341012.如题 12 图，闭合开关，当导体ab 向右运动时，电流表指针向左偏转，那么当ab 向左运动时，电流指针向右偏转，如果将磁体两极的位置对调，ab 向右运动时，电流表指针向右偏转，此过程机械能（动能）转化为电能。13.题 13 图是测量酱油密度的过程，题13-1 图可读出烧杯的质量，题13-2 图可

13、读出烧杯和酱油的总质量，题 13-3 图可读出烧杯中全部酱油的体积，那么酱油的质量m=45 g，酱油的体积V=40 cm3,酱油的密度=1.125 103 kg/m3.14.如题 14 图所示，电源电压为12V，灯泡上标有“12V 12W”，ae 和 bf 是同种型号电阻丝，每1m的电阻均为 0.5，其它导线电阻不计，c、d 两点始终保持与电阻丝良好接触，设ac 与 bd 长度均为3m，那么，小灯泡两端电压为 9.6 V。两电阻丝在100s 内产生的热为 192 J，当 c、d 两点向右移动时，文档编码:CM6M8M5K5M1 HS6H10P10Q9K5 ZU7O10L3N1N9文档编码:CM
