为节约能源，某型号汽车在关闭发动机后，通过小型发电机将减速运动时的部分动能转化为电能储存在蓄电池中．表中所示是该型号汽车的部分技术参数，其中储能效率是指汽车正常行驶时关闭发动机，直至汽车停止的过程中，通过发电机将动能转化为电能的效率．耗油量是指汽车正常行驶100km消耗燃油的体积．

测试中，先让汽车正常行驶，然后关闭发动机，分别测出开启和关闭发电机两种情况下，汽车通过的路程s与对应的速度大小v，计算出动能E_k，作出E_k﹣s图象，如图所示．

（1）发电机是根据 ____原理发电的．发电过程中，动能除了转化为电能外，由于线圈有电阻，还有部分能量转化为  ____能．

（2）汽车正常行驶100km，消耗燃油的质量为　 ____ 　kg，完全燃烧这些燃油产生的热量为　  ____　J（燃油的密度ρ=0.7×10³kg/m³，热值q=4.6×10⁷J/kg）．

（3）测试时，汽车在大小为800N的牵引力作用下，以20m/s的速度正常行驶1000m．此过程中，汽车　  ____．

A．受到的阻力为1.2×10⁴N          B．行驶的时间为40s

C．牵引力做的功为3.2×10⁸J        D．牵引力的功率为16kW

（4）由图象可知，表示关闭发电机进行测试的图线是　 ____　（选填“①”或“②”），判断的依据是 ____  ．

（5）若汽车正常行驶时的动能E_k0=4×10⁵J，某时刻关闭发动机，同时发电机开始工作，最终有   ____J的动能转化为内能．

    For hours after their boat sank, Ken Henderson and Coen trod(踏) water in the Gulf of Mexico, talking about life and death while struggling to survive. For more than 30 hours, it worked.

    Then Henderson was forced to make a decision. “I'm going to go for help or you're not going to make it,” Henderson told Coen, just before cutting the strap(带子) that connected them in the deep, cold waters. “I understand,”Coen responded, giving Henderson a last set of instructions, “Kiss my babies for me.”

    Days after the fishing trip ended in tragedy, Henderson told the story for The Associated Press.

    They had been fishing for a few hours when suddenly Coen noticed the boat was filling with water. Henderson got both motors roaring, only to have the saltwater that had leaked in break them straight away…Coen jumped to the right, his sunglasses and cap flying off. The two grabbed extra life jackets and other floating items, including a half full bottle of Diet Coke.

    “The water was so cold and it took your breath away,” Henderson said. They immediately began to tremble.

    The pair prepared for a long wait. And they talked.

“We discussed things and discussed life. We discussed families. We just tried to keep occupied,” Henderson said.

    Eventually Coen started hallucinating(有幻觉). Henderson tried to keep Coen's arms and legs moving. But as morning came, Coen's situation worsened. And so Henderson decided to cut the strap.

    He swam for two hours, tired, frustrated and depressed. Then he saw an oil rig(钻探平台) in the distance. He swam, seeing ice and crystal trees in the water. He reminded himself constantly there were no trees.

    His legs was so weak that he could barely lift them. Henderson slowly pulled himself up the rig's ladder.

    It was over 50 miles from where they had gone in the water.

    All he could think of was Coen. Convinced his friend would survive, he told the coast guard where they had parted.

    Two hours later, a fisherman found a body in a life jacket.

    Later, in the hospital, Henderson saw his friend. He apologized and asked for forgiveness. He promised to realize his wishes and look after his girls.

    “I felt like a part of me had died out there,” Henderson said.
