如图所示是一种起重机的简图，用它把质量为4× 10² kg，底面积为0.5 m²的货物G匀速提起（取g= 10 N/kg）求：

（1）起吊前，当货物静止于水平地面时，它对地面的压强是多少？

（2）若把货物匀速吊起12 m，用了40 s，则货物上升的速度是多少？

（3）起重机对货物做功的功率是多少?

（4）若OA =12 m，OB =4 m，起重机本身重力不计，吊起货物时为使起重机不翻倒，其右边至少要配质量m₀为多少kg的物体？

豆浆是对人体健康有益的饮品。如图甲是小明家的豆浆机，小明制作豆浆时发现：豆浆机先预热，再研磨，最后加热煮沸，豆浆机的铭牌如图乙所示。若把1 kg的豆浆从60℃加热到l00℃，需要豆浆机正常加热5 min，在这个过程中：

（1）若豆浆的比热容可以近似为4.2×10³ J／（kg·℃），那么豆浆吸收了多少热量?

（2）豆浆机正常进行加热时，加热电阻的阻值是多少?

（3）豆浆机正常加热5 min消耗多少电能?小明发现豆浆吸收的热量和豆浆机消耗的电能不相等，请写出一种原因。

Twelve years age I flew from my home in Minnesota to spend Father’s Day with my father in California. This wasn’t a typical Father’s Day visit, but to say goodbye to my father as his cancer rapidly advanced. We hadn’t had much of a relationship up to that day and never did much talking. He wasn’t verbal (善用言词辞的) or demonstrative (易流露感情的) nor was I. I knew he loved me simply because fathers love their children. He never told me he loved me and I never told him. That’s the way we did things in our house.

My father told me a bit about his career growth from a poor boy to a very successful businessman. He had got a lot through his hard work. He had reasons to be proud of what he had done and I had the benefit of his success. “Maybe I didn’t do things right. I never really knew you or your brothers. I did what I thought was right.” This visit didn’t change our ways. We shook hands and said goodbye as I left. Our relationship ended as we lived it.

As a father for more than 14 years I look back and understand why I am staying at home full-time with my children. I tell my children I love them every day, I hug them and I talk with them and let them know how important they are to me. However, as much as we would like to believe that we are all ideal fathers but we are not. We all made mistakes and hopefully we learned from them, just as I learned from my father.
