分为了估测大气压究竟有多大，某小组同学，在实验室合作进行了如图的实验：将蘸水的塑料吸盘按在_“粗糙”、“光滑”的水平板面上，挤出里面的空气；用弹簧测力计钩着吸盘挂钩缓慢往上拉，直到吸盘脱离板面；记录刚拉脱时弹簧测力计的读数，这就是大气对吸盘的压力F；用刻度尺测出吸盘的直径D，则大气压P=_用 F、D 表示（1）如果实验中所用弹簧测力计的量程为0-20N，吸盘与水平板面的接触面积为10cm2，当时的气压近似为一个标准大气压，则他们_“能”、“不能”测出大气压，理由是_；（2）无论怎样改良实验，用这个方法测出来的大气压数值总是偏小，最可能的原因是 _。28.6 分生活中我们常用到各种弹簧，某同学发现，用手拉不同的弹簧时，虽然都使弹簧伸长相同的长度，但是所用拉力的大小不同。因此，他猜想：使弹簧伸长相同的长度，所需拉力的大小可能与弹簧原来的长度有关。1为了验证这一猜想，他找来了细线、支架、钢丝钳和一根均匀长弹簧可裁剪，还需要准备的测量工具是_和_；2实验前，需要用钢丝钳将弹簧裁剪成长度_“相同”、“不同”的甲、乙两段；3实验时，拉伸两段弹簧，使它们都伸长相同的长度，测量对应的拉力，记录在下表：序号弹簧序号弹簧长度L/cm拉力
