某学习小组通过实验测量电源的电动势和内阻,实验室提供的器材有:
旧干电池一节(电动势约1.5V,内阻约1Ω)
电压表V(量程3V,内阻约3kΩ)
电流表A(量程0.6A,内阻约1Ω)
滑动变阻器G(最大阻值为20Ω)
开关一个,导线若干

(1)为完成实验,用笔画线代替导线,请在答题卡上完成实物图甲的连接______
(2)实验中选用旧干电池,原因是______ (简述理由);
(3)通过多次测量并记录对应的电流表示数I和电压表示数U,利用这些数据画出了UI图线,如图乙所示。由图线可以得出此干电池的电动势E=______V,内阻r=________Ω;(结果保留3位有效数字)。
(4)由于电表内电阻的影响,测量结果会有误差。答题卡上的U-I图像(如图丙)中,实线是根据实验数据描点作图得到的U-I图像。若没有电表内电阻影响的理想情况下,在UI图像中用虚线定性地描绘出电压U随电流I变化的图线______。(不用直尺、不用虚线作图均不得分)

Charles Dickens

It has been 150 years since Charles Dickens died, 184 years since his first work was released to the public and 156 years since his last completed book came out. In all of this time, these novels have never been out of print. Dickens may have left us, but his work remains timeless, 1. (fascinate) the majority of those who open their pages.

Most people have read, watched or at least heard of Dickens’ stories, but what makes him and his work so popular? Since he began novel writing in his 20s, Dickens constantly produced quality classics. Year after year his awaiting fans were not left 2. (disappoint) as their minds were fed with complex tales of romance, crime, hope and despair.

In the Victorian era he lived in, much of the work Dickens produced 3. (model) on the literature before him. He was one of the first writers of the time 4. (portray) honest examples of working-class people, giving many something to relate to. He focused on unfolding the good and bad qualities of characters which allowed his readers to follow their journeys and understand 5. they may have acted in the unusual or shocking ways that they did.

Any Dickens fans will know the diverse and outrageous (耸人听闻的) characters coming to life between the pages. 6. was special about this novelist’s ability in imagining these characters’ stories is that it comes from his own life’s path. 7. a young boy left to take care of himself in a workhouse to the wealthy figure he became through his writing successes, he knew what it was like to see in different lights. This deep understanding of his characters gave his fictional stories the strong element of believability 8. is needed in a good novel.

Over a century and a half later, Dickens’ themes can be relevant to today’s world problems. His words and imagery have been transformed further into the media of modern film, television and even musical adaptations. 9. set in a time unfamiliar to readers today, his work still enables everyone to relate to the love, hardship and sense of family that pours from the narratives. It is this aspect 10. has carried Charles Dickens into the 21st century.

如图所示,在倾角的斜面上放置一个凹槽,槽与斜面间的动摩擦因数,槽与斜面间的最大静摩擦力可认为等于滑动摩擦力,槽两端侧壁AB间的距离m。把一小球放在槽内上端靠侧壁A处,现同时由静止释放球和槽,不计球与槽之间的摩擦,斜面足够长,且球与槽的侧壁发生碰撞时碰撞时间极短,系统不损失机械能,球和槽的质量相等,取重力加速度g=10m/s2。求:
(1)释放球和槽后,经多长时间球与槽的侧壁发生第一次碰撞;
(2)第一次碰撞后的瞬间,球和槽的速度;
(3)若一开始不是由静止释放小球,而是给小球一个沿斜面向下大小为0.9m/s的初速度,试分析:球与槽的侧壁A能否发生碰撞,若能,请求出从开始释放小球到小球与侧壁A发生第一次碰撞所需要的时间是多少。
