(1)在实验中,需要测量的物理量有。A.滑板车的质量mB.圆弧形滑道的长度sC.找出滑道的最低点O,把滑板车从O点移开一小段距离至P点,由静止释放,用手机测出它完成n次往返运动的时间t

1.如图所示是用频闪周期为△t的相机拍摄的一张真空中羽毛和苹果自由下落的部频闪照片。根据提供的信息及相关数据,下列说法中正确的是()A.苹果下落的加速度大小为x3-x1t^2B.羽毛下落到C点的速度大小为x2+x32tC.一定满足关系x1:x2:x3=1:3:5D.一段时间后苹果会在羽毛下方

9.如图所示为航母电磁弹射装置的简易图,当连接舰载机的导体通有电流时,舰载机在强磁场的恒定电磁力下加速,使舰载机获得一足够的初速度,连接舰载机的导体与舰裁机的总质是为m,运动过程所受的阻力为其重力的k=0.5倍,重力加速度为g.关闭弹射装置,舰载机加速的距离为x时起飞,舰载机起飞的速度为v=2gx;如果启动弹射装置,舰载机加速的距离为时起飞,舰载机的牵引力恒定.下列说法正确的是A.关闭弹射装置,舰载机的牵引力与重力的比值为2:3B.启动弹射装置,弹射装置对舰载机做功为mgxC.启动弹射装置,弹射装置与牵引力做功之比为2:1D.仅增加电流,则舰载机加速的距离减小
