某小组同学利用长木板、毛巾、两块完全相同的带钩立方体木块、弹簧测力计等器材探究“摩擦力大小与哪些因素有关”，下表是在实验时得到的一组实验数据：

实验次数	与木块的摩擦面	木块的放置方式	弹簧测力计的示数/N
1	木板表面（水平）	一木块平放	1.8
2	木板表面（水平）	一木块平放	2.9
3	毛巾表面（水平）	一木块平放	2.4
4	木板表面（水平）	两木块叠放	3.6

（1）你认为表中哪个数据是不合理的，并指出在弹簧测力计正常使用下导致数据不合理的原因：

     2.9N

；                          是由于没有匀速拉动木块造成的

．

（2）分析第1和第4两次实验数据，可以得出结论：                           ．

（3）小丽同学提出了一个问题：摩擦力大小与接触面积是否有关呢？她将木块沿竖直方向截取一半后，测得木块所受摩擦力变为原来的一半，她由此得出：摩擦力的大小随接触面积的减小而减小，你认为她的探究过程存在的缺陷是               没有控制压力不变

．要“探究摩擦力的大小与接触面积的大小是否有关”应该选择一个     长方体

（填“长方体”或“正方体”）木块，至少需要通过做     2

次实验才能得出初步结论．

A&J Associates had been formed as a partnership firm of Ali and his cousin, Javed. Clause 2 of the partnership agreement states ‘All business of the firm shall be transacted with mutual consent of the partners’. The business of the firm is cultivation of crops in Multan. They have routinely purchased fertilisers from King Pesticides Ltd. In September 2011, Ali proposed that they purchase fertilisers from Magic Pesticides Ltd (‘MPL’). Javed opposed this proposal citing MPL’s substantially higher prices. Ali also proposed that the firm expand its business to dealing in used cars. Javed showed some interest but said that he would consider that proposal upon his return from a three month long business trip to Germany.In Javed’s absence, Ali contracted with MPL for the supply of fertilisers. Ali also contracted with Qasim to supply ten used cars. Payments to both MPL and Qasim have not been made and each has brought separate claims for recovery of amounts due against the firm before the local civil court.Required:Under the Partnership Act, 1932, advise Javed on whether he is liable for any payments due to MPL and Qasim.
