[题1](吉林省)如图1所示,用刻度尺测量物体的长度,这把尺的最小刻度值是__。所测物体的长度是__厘米.[目的]考查是否会用刻度尺测长度.[分析]仔细观察图1可知.该刻度尺的最小刻度值是1毫米(第1空答案).测量的起点对着3厘米的刻度线,物体的末端对着的刻度线为4.90厘米,故该物体的长度 L=4.90厘米-3.00厘米=1.90厘米(第二空答案). [Item 1] (Jilin Province) As shown in Fig. 1, the length of the object is measured with a scale, and the minimum scale value of the ruler is __. The length of the measured object is __cm. [Objective] To check whether the length will be measured by the scale. [Analysis] Observe Figure 1 carefully. The minimum scale value of the scale is 1 mm (the first empty answer). The starting point faces the 3 cm mark. The object’s end mark is 4.90 cm, so the length of the object L = 4.90 cm - 3.00 cm = 1.90 cm (second empty answer).
