8.t=0时刻,位于坐标原点处的波源开始沿y轴持续地上下振动,t=6.0s时刻,波恰好传播到x轴上的质点M位置,其波形图如图所示。x轴上的质点N的横坐标.xN=50cm,则下列说法正确的是yy/cm6MN11050x/cm-6A.波源振动的频率为0.2

10.如图所示,电阻不计的光滑金属导轨由直窄轨AB、CD以及直宽轨EF、GH1组合而成,窄轨和宽轨均处于同一水平面内,AB、CD等长且与EF、GH均相互平行,BE、GD等长、共线,且均与AB垂直,窄轨间距为L2,宽轨距为L.窄轨和宽轨之间均有竖直向上的磁感强度为B的匀强磁场.由同种材料制成的相同金属直棒a、b始终与导轨垂直且接触良好,棒长为L、质量为m、电阻为R.初始时b棒静止于导轨EF段某位置,a棒从AB段某位置以初速度v0向右运动,且a棒距轨端足够远,宽轨EF、GH足够长.下列判断正确的是A.a棒刚开始运动时,b棒的加速度大小为B^2L^2v03mRB.经过足够长的时间,a棒的速度为45v0C.整个过程中通过回路的电荷量为4mv05BLD.整个过程中b棒产生的焦耳热为115mv0^2

直轴线的平面上,以水面最低处为坐标原点O、以竖直向上为y轴正方向建立xOy直角坐标系,质量为m的小水滴(可视为质点)在这个坐标系下,因该“力”具有的“势能”可表示为Ep=-12nw^2x^2.该“势能”与小水滴的重力势能之和为其总势能,水会向总势能更低的地方流动,稳定时水面上的相同质量的水将具有相同的总势能,下列说法正确的是A.与该“势能”对应的“力”的大小随x的增加而减小B.稳定转动时桶中水面的纵截面为双曲线的一部分C.若增大桶的角速度ω,则稳定时,凹液面的最低点位置应下降D.小水滴距离y轴越远,该“势能”越小
