安徽省2023~2024学年度八年级综合模拟卷(二)2MNZX A AH物理试卷答案第一部分

5.高空抛物是一种不文明的行为,而且会带来很大的社会危害,一物体从高处自由落下,不计空气阻力,物体落地前1s内的位移是其下落第1s内位移的5倍,则该物体释放点距地面的高度()A.30mB.35mC.40mD.45m

安徽省2023~2024学年度八年级综合模拟卷(二)2MNZX A AH物理试卷答案第二部分（待更新）

60^6.如图所示,在某真空中有一足够大的挡板MN,它与水平方向成60°角,MN的左侧有方向垂直纸面向里、磁感应强度大小B=2T的匀强磁场。纸面内有一粒子源B=2Tm=1.0×P,P到MN的距离为0.1m,P可以沿纸面内任意方向发射大量质量m=1.0×0.1m,P10^-10kg、v=210^4m/s,10-10kg、电荷量q=+1×10C的带电粒子,粒子的速率v=2×10°m/s,不计粒q=+110^-5C子重力和粒子间的相互作用。下列说法中正确的是A.挡板MN上能接收到粒子的长度为0.2mB.若P向各个方向发射的粒子数目相等,则打在MN上的粒子数占所有粒子数的75%C.打在MN上的粒子在磁场中运动最短时间为610^-5sD.在磁场中运动时间最短的间最短的粒子的动量变化量大小为2310^-6kgm/s
