河南省2023-2024学年度八年级上学期期中综合评估【2LR】z物理第一部分

11.一列沿x轴传播的简谐横波在某时刻的波形图如图所示,该时刻质点P和质点Q偏离平衡位置的位移均为1cm,从该时刻开始计时,质点P比质点Q提前△t=0.2s回到平衡位置,则下列说法正确的是A.该波沿x轴负方向传播B.该波的传播速度大小为2cm/sC.质点P在平衡位置时,质点Q的位移一定为3cmD.质点P和质点Q在沿y轴方向上的最大距离为23cm

河南省2023-2024学年度八年级上学期期中综合评估【2LR】z物理第二部分（待更新）

15.(16分)如图所示,在xOy坐标系所在的平面内,第二象限内有沿x轴正方向的匀强电场.在x轴上S点沿y轴正方向以初速度v0(大小未知)发射质量为m、带电量为q的带正电粒子,在电场力的作用下经过时间t从y轴上的M点离开电场,测得S、M两点间的距离SM=L;若从S点沿y轴正方向发射的初速度增大为3v0,则该粒子从y轴上的N点离开电场,测得S、N两点间的距离SN=3L.不计粒子重力.求:(1)S点的坐标和粒子初速度v0的大小;(2)电场强度E的大小;(3)带电粒子运动到N点时速度vN的大小.
