14.(12分)如图所示,弹簧一端与一小物体相连,另一端悬挂于天花板上的O点,小物体置于光滑水平面上的A点,O、A在同一竖直线上且相距L0=12cm,弹簧恰好处于原长。现对物体施加水平向右缓慢增大的拉力F,当F1=9N时物体处于与A相距9cm的B点;继续缓慢增大拉力,当物体处于与B相距7cm的C点时,小物体对水平地面的压力恰好为零。不计弹簧重力,重力加速度g取10m/s^2,弹簧始终处于弹性限度内。求:(1)弹簧的劲度系数k;(2)小物体的质量m。m

(4)该小组改变两根细线的长度,测出多组双线摆的摆长/和振动周期T1,作出7^2-1图像如图丙所示(图像未过原点),则利用图像所求重力加速度准不准确,为什么?▲▲.
