写信向你询问有关风筝的一些情况

请你给他写一封回信，内容包括：英语试题第7页（共8页）

②②某同学实验中最终测得的油酸分子直径偏大,其原因可能是A.错误地将油酸酒精溶液的体积直接作为油酸的体积进行计算B.估算油酸膜的面积时,错将所有不完整的方格均作为完整方格处理C.水面上爽身粉撒得较多,油酸膜没有充分展开D.数每毫升油酸酒精溶液的滴数时,多数了2滴

4.如图所示,绝缘粗糙的竖直墙壁右侧同时存在电场强度大小为E、方向水平向左的匀强电场和磁感应强度大小为B、方向垂直于纸面向里匀强磁场。质量为m,电荷量为q(q>0)的小滑块(可视为质点)从A点由静止开始沿墙壁下滑,至C点时离开墙壁,沿CD段做曲线运动,到达D点时速度最大,已知滑块与墙壁间的动摩擦因数为,重力加速度为g,,则下列说法正确的是A.从A点运动到C点的过程中滑块做匀加速直线运动B.滑块到达D点时的加速度为零C.D点为滑块运动轨迹的最低点D.若已知A、C两点之间的高度差,则可求出从A点运动到C点的过程中摩擦力对滑块做的功

(2)图中点是小球抛出点在水平地面上的竖直投影,实验时先让入射小球多次从斜槽上位置S由静止释放,通过白纸和复写纸找到其平均落地点的位置P,测出平抛射程OP,然后把半径相同的被碰小球静置于轨道的水平部分末端,仍将入射小球从斜轨上位置S由静止释放,与被碰小球发生正碰,并多次重复该操作,两小球平均落地点位置分别为M、N。实验中还需要测量的物理量有。(选填选项前的字母)A.人射小球和被碰小球的质量m1、m2B.入射小球开始的释放高度hC.小球抛出点距地面的高度HD.两球相碰后的平抛射程OM、ON
