2.2023年7月20日,“神舟十六号”航天员圆满完出活动全部既定任务。天员在出时穿的给热航天服中气体视为理想气体,出龄前航天服中理想气体的速率分布直方如图甲所示(图中飘坐标f(x)为“速率ν附近单位速率区间内的分子数占总分子数的百分比”、横坐标为“分子的速率”)。航天员出检后,若不采取任何精,航天服中系气体的速率分布直方图可能为

11.如图所示,竖直平面内固定一根竖直的光滑杆P和p水平光滑杆Q,两杆在同一平面内,不接触,水平杆延长线与竖直杆的交点为O.质量为2m的小球A套在竖直杆上,上端固定在杆上的轻质弹簧的另一端与小球A相连.另一质量为m的小球B套在水平杆Q上,小球A、B用长为2L的轻杆通过链分别连接.在外力作用下,当轻杆与水平杆Q成=53^斜向左上时,轻质弹簧处于原长,系统处于静止状态.撤去外力,小球A在竖直杆上做往复运动,下降的最大距离为2L.已知轻质弹的弹性势能Ep=12kx^2,x为弹簧的形变量,k为轻质弹簧的劲度系数,整个过程轻质弹簧始终处在弹性限度内,不计一切摩擦,重力加速度大小为g,53^=0.8,53^=0.6.则下列说法正确的是A.轻质弹簧的劲度系数k为-2mgLB.小球A运动到O点时的速度大小为452gLC.从撤去外力到轻杆与水平杆Q成=30^斜向左上的过程,轻杆对小球B做的功为21175mgLD.小球A从最高点运动到O点的过程,水平杆Q对小球B的作用力始终大于:mg

(2)如图b所示,撤去(1)中的拉力,现只用一个弹簧测力计通过细绳沿平行于木板的方向拉橡皮筋,要将橡皮筋的B端拉至,这样做的目的是;记下细绳的方向,并读出拉力的大小为F=2.20N;
