(1)求m的值;

(2)求方程的解.

4.

有一种轮子会发光的溜冰鞋,轮子是透明的,磁环固定在轮周上,由金属线圈和发光二极管组成的闭合电路固定在轮的轴上。溜冰时磁环随轮周转动,相当于金属线圈做 {#blank#}1{#/blank#}  运动,电路中产生 {#blank#}2{#/blank#}  ,从而使发光二极管发光,这个过程中能的转化是 {#blank#}3{#/blank#}  。

5.

如图所示,ab为闭合电路的一部分导体,当ab在磁场中运动时,能产生感应电流的是 {#blank#}1{#/blank#} 。

A.垂直纸面向里运动        B.垂直纸面向外运动

C.沿纸面向右运动          D.沿纸面竖直向上运动

理由: {#blank#}2{#/blank#} 

6.

一元二次方程a(x﹣1)2+b(x﹣1)+c=0化为一般形式后为2x2﹣3x﹣1=0,试求a,b,c的值.

7.

探究导体在磁场中运动时产生感应电流的条件如图所示,实验时,控制磁场方向相同,改变导体ab的运动方向.

步骤一:导体水平左右运动,如图甲所示,电流计指针 {#blank#}1{#/blank#}  ,这是因为 {#blank#}2{#/blank#}  .

步骤二:导体竖直上下运动,如图乙所示,电流计指针 {#blank#}3{#/blank#}  ,这是因为 {#blank#}4{#/blank#}  .

步骤三:导体水平左右运动,如图丙所示,电流计指针偏转,电路中有电流产生.

8.

如图所示,R0是一个光敏电阻,光敏电阻的阻值随光照强度的增加而减小,R是电阻箱(已调至合适阻值),它们和继电器组成自动控制电路来控制路灯,白天灯熄,夜晚灯亮。下列说法正确的是(  )

9.

小明同学的弟弟饭前总不爱洗手,为让他养成饭前洗手的卫生习惯,小明利用自己所学的知识,和弟弟在家里做了如下的实验探究:

找三个相同的馒头袋,一起放在蒸锅里蒸30分钟.待冷却后起盖,让弟弟尽快用手在甲馒头上按一下,再用肥皂把手认真洗干净后,用同一手指在乙馒头上按一下.丙馒头上不用手按.然后用无菌工具迅速将三个馒头别装入相同的洁净塑料袋(医用,无菌)并密封好.一起放在温暖的地方,过一段时间后,观察甲、乙、丙馒头的变化.
