(3)他又利用本实验原理把该弹簧做成一把 弹簧秤，当弹簧秤上的示数如图(c)所示时，该 弹簧的长度x＝______________cm．
答案：(1)竖直 (2)4,50 (3)10
解析：(1)弹簧是竖直的，要减小误差，刻度尺必须与弹簧平行，故刻度尺要保 持竖直状态；
(2)弹簧处于原长时，弹力为零，故原长为 4 cm；弹簧弹力为 2 N 时，弹簧的长 度为 8 cm，伸长量为 4 cm；根据胡克定律 F＝kΔx，有：k＝ΔFx＝0.204Nm＝50 N/m；
4．按照在图中所绘点的分布与走向，尝试
某同学利用如图(a)装置做“探究弹 簧弹力大小与其长度的关系”的实验．
(1)在安装刻度尺时，必须使刻来自尺保持 ____________状态．
(2)他通过实验得到如图(b)所示的弹力大小 F与弹簧长度x的关系图线，由此图线可得该弹 簧的原长x0＝____________cm，劲度系数k＝ ____________N/m．
(4)根据 Y＝kSL求得，Y≈4.98×106 Pa．
答案：(1)D (2)毫米刻度尺 螺旋测微器 (3)见解析图 312.5 (4)4.98×106 Pa
减小实验误差的两种方法
本实验的系统误差来自弹簧的重力，所以 改进实验的思路应该是尽可能减小弹簧自重的 影响：
(1)一个方案是选择劲度系数较小的轻弹 簧，通过减小读数的相对误差来提高实验的精 确度．
(1)在国际单位制中，杨氏模量 Y 的单位应该是( )
A．N
B．m
C．N/m
D．Pa
(2)有一段横截面是圆形的橡皮筋，应用如 图所示的实验装置可以测量出它的杨氏模量Y 的值．首先利用测量工具a测得橡皮筋的长度L ＝20.00 cm，利用测量工具b测得橡皮筋未受 到拉力时的直径D＝4.000 mm，那么测量工具 a应该是____________，测量工具b应该是
