A woman called Julia lived in the countryside, one year she decided to visit the capital city to see the sights. She stayed at a hotel near the central market. She had seldom been to the city before, and was very excited about what she would find.

On the first morning of her visit, as she walked from the hotel to the market, she passed a beggar (乞丐). He was holding up a notice, which said, “Blind from birth. Please give generously(慷慨地).”Julia felt sorry for the beggar and she bent down and put a dollar coin into his bowl. “Thank you.” he said. The same thing happened again the following day. On the third day, however, Julia did not have a dollar coin. She had only fifty cents, so she dropped this into the beggar’s bowl. “What have I done wrong?” the beggar said, “Why are you so stingy (吝啬的) today?”

Julia was very surprised at the beggar . “How do you know I haven't given you a dollar?” she said, “If you’re blind you can't know what coin I put into your bowl.” “Ah,” explained the beggar, “The truth is that I'm not blind. I'm just looking after this place for the regular beggar while he’s on holiday.” “On holiday?” Julia said, “And what exactly does your blind friend do on holiday?” “He goes into the countryside,” the man said, “and takes photographs. He's a very good photographer.”

某同学用如图（a）、（b）、（c）所示实验研究物体运动与受力之间的关系，他用测力计拉着小木块在长木板上沿水平方向从A匀速移动到B如图（a）所示，记下测力计的示数为1牛。将长木板竖直放置如图（b）所示，用测力计吊着小木块沿竖直方向从A匀速移到B，记下测力计的示数为5牛。用测力计吊着小木块静止在位置B如图（c）所示，记下测力计的示数也为5牛。已知木块的的重力为5牛，木块与水平面间的滑动摩擦力为1牛。

（1）分析图中（a）和（b）可得：当物体受力                   时，物体处于匀速直线运动状态。

（2）分析图中（a）、（b）、（c）可得：                                                                         。
