小王同学到通江溶洞玩耍时在洞内捡到一个形状奇特且不溶于水的物体他想知道这个不明物体是由什么材料构成于是在实验室进行了如下操作 1他先将天平放在水平桌面上移动游码至标尺左端零刻度处发现指针静止在分度盘中央的右侧则应将平衡螺母向调节直至天平平衡. 2在用调节好的托盘天平称量物体的质量时往右盘中加入最小的砝码后发现指针在分度盘上的位置如图丙所示.接下来的操作应是填“取出”或“不取出”最小的砝码向填“左”或“右”移动填“游码”或“平衡螺母”. 3当天平平衡时盘中所加砝码和游码位置如图甲所示时则此物体的质量为g 4在量筒内装有一定量的水该物体放入前后的情况如图乙所示则物体的体积是cm3物体的密度是g/cm3.参考密度表物质的密度该物体是由构成. 5实验中所用细线会对测量结果造成一定误差导致所测密度值填“偏大”或“偏小”.
对生活中一些惯性现象的解释 ①水平公路上行驶的汽车关闭发动机后还能继续行驶一段距离.是因为汽车具有惯性 ②跳远运动员助跑起跳是为了增大惯性 ③小汽车配置安全气囊可以减小惯性带来的危害 ④抛出去的实心球还会在空中运动一段时间是因为实心球受到惯性力的作用. 以上四种说法中正确的是

小明同学在做“探究凸透镜成像现律”的实验. 1如图甲小明让平行光正对凸透镜照射光屏上出现一个最小最亮的光斑则凸透镜的焦距f=cm.实验前应调节烛焰凸透镜光屏三者的中心使它们在选填“同一直线”或“同一高度”上. 2实验过程中当蜡烛与占透镜的距离如图乙所示时在光屏上可得到一个清晰的倒立缩小的实像生活中利用这个规律制成的光学仪器是.选填“照相机”“放大镜”或”投影仪” 3如图丙所示保持蜡烛位置不变移动透镜至16cm刻度线处则人眼在选填“ABC”处能观察到烛焰的像像是图丙中的选填“1234”. 4在图乙实验完成之后小莉把自己的近视眼镜放在蜡烛与凸透镜之间如图丁所示光屏上原来清晰的像变得模糊了若想在光屏上重新得到清晰的像在不改变蜡烛和凸透镜位置的情况下应将光屏凸透镜.选填“靠近”或“远离”
