Let's go to Dongfang Clothing Store. It's that time of year again! The store is great sale! There are lots of things at a very good price in the store. They have T-shirts in all colors for 30yuan each. They have bags for both sports and school. They sell them for only 15 yuan. They have black sweaters for only 20 yuan. They have long white socks for only 5 yuan. And that's not all. You can go to the store and see for yourself.根据短文内容，判断下列句子正(T)、误(F)。 （1） At that time of year, the clothes are very cheap in Dongfang Clothing Store. （2） Ther在探究加速度与物体质量、物体受力的关系的活动中，某小组设计了如图甲所示的实验装置．图中上下两层水平轨道表面光滑，两小车前端系上细线，细线跨过滑轮并挂上砝码盘，两小车尾部细线连到控制装置上，实验时通过控制装置使两小车同时开始运动，然后同时停止．（1）在安装实验装置时，应调整滑轮的高度，使；在实验时，为减小系统误差，应使砝码盘和砝码的总质量（填“远大于”“远小于”或“等于”）小车的质量．（2）本实验通过比较两小车的位移来比较小车加速度的大小，能这样比较，是因为 ．（3）实验中获得数据如下表所示：小车Ⅰ、Ⅱ的质量m均为200g实验次数小车拉力F/N位移x/cm1Ⅰ0.1Ⅱ0.246.512Ⅰ0.229.04Ⅱ0.343.633Ⅰ0.341.16Ⅱ0.444.804Ⅰ0.436.43Ⅱ0.545.56在第1次实验中小车Ⅰ从图中的A点运动到B点（测量结果如图乙标尺所示），请将测量结果填到表中空格处 ． 通过分析，可知表中第次实验数据存在明显错误，应舍弃．
