(9分)某实验小组探究弹簧的劲度系数k与其长度(圈数)的关系;实验装置如图(A)所示:一均匀长弹簧竖直悬挂,7个指针p0、p1、p2、p3、p4、p5、p6分别固定在弹簧上距悬点0、10、20、30、40、50、60圈处;通过旁边竖直放置的刻度尺,可以读出指针的位置,p0指向0刻度;设弹簧下端未挂重物时,各指针的位置记为x0;挂有质量为0.100kg砝码时,各指针的位置记为x;测量结果及部分计算结果如下表所示(n为弹簧的圈数,取重力加速度为9.80m/s2).已知实验所用弹簧的总圈数为60,整个弹簧的自由长度为11.88Cm.&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp&nBsp 将表中数据补充完整:{{u}} ① {{/u}},{{u}} ② {{/u}};
