(3)多次改变滑动变阻器的阻值,电压表示数记为U,电流表的示数记为I,记录多组U-I值,绘制出U-I图像如图乙所示,若该直线的斜率k=2985Ω,,则待测电阻Rx的测量值为(结果
15.(14分)如图所示,光滑水平面上有一个圆心角为60^的光滑圆弧轨道,轨道底端与水平面相切。初速度大小为v0的小球(可视为质点)从水平面滑上圆弧轨道,小球从圆弧轨道飞出时的速度方向与水平方向成30^°角,已知小球质量为m,,圆弧轨道的半径为R=v0^22g,分离时小球与轨道在垂直于接触面方向上的速度分量相等,不考虑空气阻力,重力加速度为g,求:(1)圆弧轨道的质量;(2)从小球滑上圆弧轨道到与圆弧轨道分离时轨道对小球做的功;(3)小球再次回到飞出时的高度时与圆弧轨道的最高点之间的水平距离。
3.如图所示,空间内存在方向竖直向上、电场强度大小E=110^4N/C的匀强电场,三个小球用不可伸长的绝缘细线相连悬挂于电场中的点,已知质量分别为mA=0.5kg,mB=0.3kg和mc=0.2kg,,小球A、C不带电,小球B带电量q=-210^-4C,重力加速度g取10m/s^2。则烧断AO之间细线的瞬间,小球B的加速度大小为A.503m/s^2B.252m/s^2C.10m/s^2D.6m/s^2
