17.利用如图所示的装置研究“磁场对电流的作用”时,应在a、b之间接人灵敢电流计;若在a、b之间接人电源可研究“电磁感应现象”。(均选填“灵敏电流计”“电源”或“灯泡”)
的缓冲转运装置,卸货时飞机和缓冲装置A固定不动,转运车B靠紧A。包裹C沿缓冲装置A的光滑曲面由静止滑下,经粗糙的水平部分,滑上转运车B并最终停在转运车B上被运走,B的右端有一固定挡板。已知C与A、B水平面间的动摩擦因数均为=0.4,,转运车B与地面间的摩擦可忽略。转运车B的质量为M=60kg,A、B水平部分的长度均为L=4m。。某包裹C质量为m=20kg,可视为质点且无其它包裹影响,重力加速度g=10m/s^2。C与B的右挡板发生碰撞时间极短,碰撞时间和损失的机械能都可忽略。(1)若该包裹从h=2.4m高度处由静止滑下,在缓冲装置A的光滑曲面上经t=135s滑入粗糙水平轨道,求此包裹在曲面运动过程中合外力冲量大小和受到的重力冲量的大小;(2)若该包裹从h=2.4m高度处由静止滑下,求此包裹在距转运车B右端多远的位置不再相对B滑行;(3)为使该包裹能滑上并停在转运车B上,则该包裹释放时h的范围。(结果保留两位有效数字)ChAB
10.电阻不计,相距为L的光滑水平金属导轨处于磁感应强度大小为B、方向竖直向上的匀强磁场,导轨右端接入阻值为R的定值电阻,如图甲所示。质量为m,电阻为r的金属棒ab在向左的水平拉力作用下,由静止开始运动,运动过程中始终与导轨垂直,并保持良好接触,其速度一时间图像如图乙所示,图中所标的vm、T为已知量。下列说法正确的是B.时时时间内,水平拉力随时间变化的关系为F=2B^2L^2vm(R+r)Tt+2mv0T时间内,水平拉力随时间变化的关系为F=2B^2L^2vm(R+r)Tt-2mv0TC.0∼T时间内,安培力的冲量大小为B^2L^2vaTR+rD.0T时间内,安培力的冲量大小为B^2L^2vnT2(R+r):
