随着人们生活水平的逐渐提高，小轿车已经走进了千家万户．前不久，小明家也新买回来了一辆小汽车，好奇的小明找出了小汽车如下表列出的有关数据：（g=10N/kg，1L=10^﹣3m³）

求：（1）该小汽车静止在水平地面上时，对地面的压强是多大？

（2）若该小汽车行驶100km，则需耗油多少千克？

（3）小明发现该小汽车在水平路面上以额定功率匀速运动的速度是72km/h，请计算该车行驶100km牵引力所做的功．

（4）假如小明还想知道小汽车发动机正常工作时的效率大约是多少，则小明还需查阅的信息有哪些？

这份成长中的友谊，将使我们宝贵的初中生活更加精彩，____充满阳光。

真山民^①

愁锁巴云往事空，只将遗恨寄芳丛。归心千古终难白，啼血万山都是红。

枝带翠烟深夜月，魂飞锦水^②旧东风。至今染出怀乡恨，长挂行人望眼中。

【注】①真山民，宋朝遗民，真名不详。宋亡后隐姓埋名，好题咏，自称山民。②锦水：即锦江，在四川成都。
