1.地球上各处的地形地貌会影响风的形成。由于海水的比热容与陆地上沙石的比热容1.不同,于是在白天,接受相同太阳辐射能,陆地空气升温较(选填“快”或“慢”),空气上升形成海面吹向陆地的海陆风,晚上则反之

安徽省2024-2025学年上学期宿州市埇桥区南方学校七年级入学考试(物理)试卷答案

7.如图所示,倾角为20^的足够长的质量为M的斜面体B静止在水平地面上,质量为m的滑块A以一定的初速度沿斜面向下滑动,t=0时刻对A施加一沿斜面向下的作用力F,使A沿斜面向下做匀速直线运动。t=2s时改变F的大小及方向,使滑块依然匀速下滑,t=4s时撤去F,t=6s时,A恰好静止在B上,已知滑块与斜面之间的动摩擦因数q=0.75,B始终处于静止状态,重力加速度为g37^=0.75,.下列说法正确的是时间内,B对地面的压力小于(M+m)gB.0∼1s时间内,B对地面的摩擦力方向水平向左时间内,当F与水平方向夹角为33^且指向左上方时,F有最小值D.t=3s与t=5s时,地面对B的摩擦力大小相等

(2)该同学得到了7组实验数据,如下表所示。在图(b)所示的坐标纸上已经描好了7组数据点,请在答题卡上的坐标纸中作出x-L图像。(3)由图像可得,物块与桌面之间的动摩擦因数=。(已知37^=0.6,37^=0.8,,结果保留2位有效数字)
