Most children have wonderful toys to play with. Usually, their parents buy these toys for them, often as Christmas or birthday gifts. Some children buy small toys with their pocket money. But instead of buying toys, one fun way to get new toys is to make them.
The easiest toy to make is a kite. For a kite, all you need is a large piece of paper, two sticks, some pieces of string and some glue. Take the two sticks and use the string to fix them together in the centre.Then take a string and tie it to the ends of the sticks to make a string square (IE #). Cut the paper to make it the same size as the square. Finally, stick the paper to the string square with glue, Now your kite is finished. All you need to do is to tie a long string to the kite so you can fly it. In many countries, there are kite competitions. Hundreds of people come together to show off their kites. In one famous competition, some of the kites are more than three metres tall. They need many strong men to fly them and people use rope instead of string

(2)第1次实验时，弹簧测力计示数如图所示，为 N，由表格数据可得，此次测得滑轮组机械效率为 %(结果精确至0.1%)。
(3)分析序号为1、2、3的三次实验数据可知，用同一滑轮组提升重物时，重物越重，机械效率越 (选填“高”或“低”)；分析序号为 的两次实验数据可知，滑轮组的机械效率与钩码上升高度 (选填“有关”或“无关”)。
(4)换用更重一些的动滑轮重复第2次实验，测得的机械效率会 (选填“大于”“等于”或“小于”)62.5%。
20.(7分)利用铁架台、杠杆、钩码和弹簧测力计等器材探究杠杆的平衡条件，实验使用的钩码质量均相等，杠杆上每格长度均相等。
(1)实验前，杠杆静止时如图甲所示，此时杠杆处于 (选填“平衡”或“非平衡”)状态，为使杠杆在水平位置平衡，需将平衡螺母向 (选填“左”或“右”)调节。
(2)如图乙所示，多次改变杠杆两侧悬挂的钩码的个数并移动钩码的位置，使杠杆在水平位置
平衡，此时使杠杆在水平位置平衡的目的是为了便于 。实验中，杠杆在水平位置平衡时记录的数据如下表所示，分析数据可得出杠杆的平衡条件： (用表格中的物理量符号表示)
