（1）发电站通过升压变压器、输电导线、降压变压器把电能输送到用户，如果升压变压器和降压变压器都可视为理想变压器，当发电机的输出功率为100kW，输出电压为250V，升压变压器的原副线圈匝数比为1：25，求升压变压器的输出电压和输电导线上的电流．

（2）如图所示，在光滑的水平面上放着一个质量为M=0.3kg的木块（可视为质点），在木块正上方h=1m处有一个固定悬点O，在悬点O和木块之间用一根长L=2m的不可伸长的轻绳连接．有一个质量m=0.1kg的子弹以v₀=80m/s的速度水平射入木块并留在其中，后木块能运动到圆周的最高点，（g取10m/s²），求木块离开水平地面速度大小和木块到达最高点时轻绳对木块的拉力的大小．

Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.

“ I think we are knocking at the door of immortality (永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “ I think by 2075 we will see it and that’s a conservative estimate.”

At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(纳米技术) make it likely that humans will live in the future beyond what has been possible in the past. “ There is a great push so that people can live from 120 to 180 years,” he said. “ Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”

However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.

Scientists also differ on what kind of life the super aged might live. “ It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?” said Leonard Poon, director of the University of Georgia Gerontology Center. “ At present people who could get to that point are not in good health at all.”
