A university in Wuhan, Hubei province, recently launched a fitness app to encourage students to exercise, the Paper reported on Wednesday.

Hubei University of Economics requires its students to run at least 30 times a semester, and only one record each day will be added to undergraduate's PE result.

For freshman and sophomore students, their running record will account for 30 percent of PE result. Junior students have to finish the required running times before they take the physical fitness test.

From 6 am to 10 pm, students can sign in the app that will give them two fixed sites according to their location in the campus. Students can get a record after they clock in the two set sites.

Data shows that 11,000 students are using the app and the average mileage has

reached 10 kilometers from October 16 to 26.

Cui Gaoyuan, director dean of sports economics and management school, told the Paper, the university launched the app in order to encourage students to exercise more and form a good habit.

Liu Yue, a student from school of journalism, who runs at least three kilometers a day, said, "The record is related to our results, so it is good to encourage us to do exercise."

Li Yongen, a student from sports management major, said, "I run and go to gym four or five times a week. I think running to fulfill tasks may influence exercise quality."

Cui said students will fail if they are found cheating in running.

percent of PE result.对于大一和大二的学生来说,他们的跑步记录将占体育成绩的30%,在文中第三段

设置的网站上看到他们的记录,文中第四段最后一句

(1)分析比较图中(a)(b)两图中的装置、操作和现象,归纳得出初步结论:当相互连接的两种金属丝的材料不变时,接触点之间的温度差越小,电路中的电流________.(2)分析比较图中(a)(c)两图[或(b)(d)两图],发现当相互连接的两种金属丝的材料相同,金属导线接触点之间的温度差也相同,且用酒精灯对金属导线中部进行加热时,闭合回路中的电流表示数________(选填“变大”、“不变”或“变小”).据此可得出初步结论:当相互连接的两种金属丝的材料相同,金属导线接触点之间的温度差也相同时,电路中的电流大小与金属导体中部温度高低________. 【答案】越小不变无关 【解析】 【分析】 【详解】 (1)比较a、b两次实验可知,当相互连接的两种金属丝的材料不变时,(a)中冰水混合物与酒精灯火焰的温度差比较大,电流表示数大;(b)中开水与酒精灯火焰的温度差较小,电流表的示数小,故可得出的结论为:当相互连接的两种金属丝的材料不变时,接触点之间的温度差越小,电路中的电流越小;(2)分析比较图中(a)(c)两图(或(b)(d)两图),发现当相互连接的两种金属丝的材料相同,金属导线接触点之间的温度差也相同,且用酒精灯对金属导线中部和最长处进行加热时,闭合回路中的电流表示数相同,据此可得出初步结论:当相互连接的两种金属丝的材料相同,金属导线接触点之间的温度差也相同时,电路中的电流大小与金属导体中部温度高低无关. 【点睛】 根据图示判断两个接触点的温度差,然后比较实验中电流表的示数,并与已有的结论对比. 2.如图所示的电路中,电源电压为U,闭合电键S,发现两电表指针的位置均不变,已知故障只发生在电阻R1、R2上,请根据相关信息写出电压表的示数及相应的故障.

一、初一数学有理数解答题压轴题精选(难) 1.同学们都知道表示5与-2之差的绝对值,实际上也可理解为5与-2两数在数轴上所对的两点之间的距离,试探索: (1)求 ________. (2)找出所有符合条件的整数,使得.满足条件的所有整数值有________ (3)由以上探索,猜想对于任何有理数x,是否有最大值或最小值?如果有最大值或最小值是多少?有最________(填“最大”或“最小”)值是________. 【答案】(1)7 (2)-3,-2,-1,0,1,2; (3)最小;3 【解析】【解答】(1)原式=|5+2|=7. 故答案为: 7;(2)令x+3=0或x-2=0时,则x=-3或x=2. 当x<-3时,- (x+3) - (x-2) =5 , -x-3-x+2=5,解得x=-3(范围内不成立) 当-3≤x≤2时,(x+3) - (x-2) = 5, x+3-x+1=4,0x=0,x为任意数, 则整数x=-3,-2,-1, 0,1, 当x>2时,(x+3) + (x-2) = 5, x=2(范围内不成立) . 综上所述,符合条件的整数x有: -3, -2, -1, 0,1,2. 故答案为:-3,-2,-1,0,1,2;(3) 由(2) 的探索猜想,对于任何有理数x,有最小值为3, 令x-3=0或x-6=0时,则x=3,x=6 当x<3时,-(x-3)-(x-6)=-2x+3﹥3 当3≤x≤6时,x-3-(x-6)=3, 当x>6时,x-3+x-6=2x-9>3 ∴对于任何有理数x,有最小值为3 【分析】(1)直接去括号,再按照去绝对值的方法去掉绝对值就可以了;(2)要求x的整数值可以进行分段计算,令x+3=0或x-2=0时,分为3段进行计算,最后确定x的值.(3)根据(2)方法去绝对值,分为3种情况去绝对值符号,计算三种不同情况的值,最后讨论得出最小值. 2.如图,数轴的单位长度为1,点,,,是数轴上的四个点,其中点,表示的数是互为相反数.
