(1)用游标卡尺为20分度的卡尺测量某工件的内径时,示数如图甲所示,由图可知其长度为_______cm;用螺旋测微器测量某圆柱体的直径时,示数如图乙所示,由图可知其直径为______mm.

(2)某同学采用如图1所示的装置探究物体的加速度与所受合力的关系。用砂桶和砂的重力充当小车所受合力F;通过分析打点计时器打出的纸带,测量加速度a。分别以合力F 和加速度a作为横轴和纵轴,建立坐标系。根据实验中得到的数据描出如图2所示的点迹,结果跟教材中的结论不完全一致。该同学列举产生这种结果的可能原因如下:

(1)在平衡摩擦力时将木板右端垫得过高;

(2)没有平衡摩擦力或者在平衡摩擦力时将木板右端垫得过低;

(3)砂桶和砂的质量过大,不满足砂桶和砂的质量远小于小车质量的实验条件;

(4)测量小车的质量或者加速度时的偶然误差过大。
