2024年陕西省西安市莲湖区五校联考中考模拟物理试卷答案第一部分
15.(18分)如图所示,倾角为0的光滑斜面体固定在水平面上,斜面底端固定一挡板。三个相同θ的小物块A、B、C,质量均为m,小物块A紧靠挡板放置,小物块A和小物块B通过劲度系m数k=mg2L的轻质弹簧相连,开始时A、B均静止。现让小物块C沿斜面从小物块B上端L处由静止释放,小物块B、C碰后一起向下运动(未粘连),当B、C再次分离后撤去小物块C。已知弹簧的弹性势能可表示为Ep=12kx^2,kk为弹簧的劲度系数,x为弹簧的形变量,重力加速度为g^∘(1)求小物块B碰后瞬时速度的大小;(2)求小物块B向下运动的最大位移;(3)现让小物块C沿斜面从小物块B上端另一位置由静止释放,若小物块B沿斜面向上运动到最高点时,小物块A恰好离开挡板,求小物块C开始下落时距小物块B的距离。

(1)A、B两个兴趣小组分别利用实验电路图甲进行实验。①A组方案主要步骤如下:a.闭合开关S1,单刀双掷开关S2扳到“1”位置,调节电阻箱R1,使电流表为某一适当的读数I,测量并记下空笔芯里盐水的长度L1;b.保持R1不变,开关S2扳到“2^”位置,调节R2使得电流表读数为I时,R2的读数即为长度为L1的盐水的阻值;c.改变笔芯管内盐水柱长度,重复实验步骤a、b,记录每一次盐水柱长度L和电阻箱R2阻值R,画出的R-L图线如图乙所示的(填“I线”或“Ⅱ线”),根据测得的空笔芯内径d和该图像中标注的有关字母,可得盐水的电阻率表达式为。②B组方案主要步骤如下:a.闭合开关S1,,单刀双掷开关S2扳到“1”位置,调节电阻箱R1,,使电流表为某一适当的读数I,测量并记下空笔芯里盐水的长度L1和电阻箱的读数R;b.开关S2始终扳到“1”位置,改变笔芯管内盐水柱长度,调节R1使得电流表读数为I时,记录每一次盐水柱长度L和电阻箱R1阻值R,画出的R-L图线如图乙另一条直线;c.该小组根据测得的空笔芯内径d和该图像中标注的有关字母,可得盐水的电阻率表达式为.
