三、计算与推导题(第17小题7分。第18小题6分。共13分)解答要有必要的公式和过程。只有最终答案不能得分。
17.阿基米德桥是一种基于阿基米德原理、被固定于水面以下的封闭通道,是一种跨越水域的新交通方式。图7是阿基米德桥示意图。与一般的桥也不同,阿基米德桥借
助于浮力浮于水中,对于浮力大于重力的阿基米德桥,它和水底的连接方式与桥相反——用缆索固定于水底和两岸。
(1)请在图中画出缆索对桥体的力的示意图。(画出一根缆索上的力即可)
(2)浙江省计划在千岛湖建造一个长为L、截面为S、符合环保要求的水下悬浮隧道——“阿基米德桥〞。请推导出该桥受到的浮力F浮。若桥自身质量为m0,推导出该桥的最大承载量为m。(ρ水、g已知)
18.发光二极管是一种发展前景十分好的节能灯具,它将取代白炽灯而成为主流照明灯具。试验发现,4只“2.5V10mA〞的高亮发光二极管和1只“2.5V0.3A〞的白炽灯在正常工作时光照强度一致。
(1)请计算在正常发光的状况下高亮发光二极管和白炽灯光照强度一致时的功率之比;
(2)你认为在功率一致的状况下,发光二极管比白炽灯亮得多的原因是什么?
19.质量是物体的一个基本属性,与物体的状态、外形、所处的空间位置变化无关。小明想通过试验探究这一观点。
(1)他首先用天平测出一空烧杯的质量为50g,接着从冰箱里取出一正方体冰块,冰块截面如图8甲(1:1大小)所示,请根据图形测出该冰块的边长为cm。小明将冰块放入烧杯,在天平右盘增加了5g的砝码,再将游码移至如图8乙所示位置时天平平衡,该冰块的质量为g,小明算出冰块的密度为g/cm3。
(2)小明算完冰块的密度后,发现天平不再平衡,指针如图8丙所示,通过细心观测,看到冰块表面有水珠出现,于是小明得出结论:物体的状态发生变化时,质量可能改变。请分析天平失去平衡的原因并对小明的试验过程进行评估。
20.小明同学准备做“凸透镜成像〞的试验,他先将凸透镜对着太阳光,调整凸透镜和白纸间的距离,直到太阳光在白纸上会聚成一个最小、最亮的点,请在图9A中完成这一过程的光路图,并在图中标出白纸的位置;
接着他在光具座上依次放置蜡烛、凸透镜和光屏,点燃蜡烛,移动光屏,发现在光屏上出现如图9B所示的现象,其原因是。调整后在光屏上得到了清楚的放大的像。小明还想探究成缩小实像的规律,具体操作是
21.如图10所示,是测量小灯泡电功率的实物元件图,其中电源是由三只蓄电池组成,小灯泡额定电压是3.8V,其灯丝电阻约为10Ω,滑动变阻器标有“10Ω、1A〞字样,电流表(0~0.6A、0~3A),电压表(0~3V、0~15V).
(1)请用笔画线代替导线,把右图中的电路元件连接成试验电路.
(要求:滑片P向左移时灯变亮,且连线不得交错)
(2)小明合理地连接好电路,并按正确的顺序操作,闭合开关后灯不亮,小明猜想:
A.可能灯丝断了B.可能是变阻器开路C.可能是小灯泡短路
请你借助电路中的电流表和电压表验证小刚的猜想,并填入上表.
(3)排除故障后,小明继续试验,调理滑动变阻器滑片,使电压表示数为V时,小灯泡正常发光,此时电流表示数如图11所示,则小灯泡的额定功率是w
物理学中对于一些看不见摸不着的现象或不易直接测量的物理量,寻常用一些十分直观的现象去认识或用易测量的物理量间接测量,这种研究问题的方法叫转换法。主要是指在保证效果一致的前提下,将不可见、不易见的现象转换成可见、易见的现象;将陌生、繁杂的问题转换成熟悉、简单的问题;将难以测量或测准的物理量转换为能够测量或测准的物理量的方法。
22.伽利略在研究自由落体运动时,利用滴漏法来测时间,就是转化法的应用。图12所示是滴漏法测时间的水钟原理图,关于这个测量说法错误的是:()
A.它将时间测量转换为水面高度变化的测量
B.中间蓄水池浮子水塞利用浮力保证恒定水位,以确保其流出的水滴速度均匀
C.时间测量就是长度的测量
D.假如没有重力,这个测量就无法进行
23.图13为我们试验室所用电流表的内部结构示意图。当接入电路,有电流通过线圈时,线圈带动指针偏转。测量时首先把强弱变化的电流转换为线圈受力大小的变化,其物理原理是;
再将线圈受力的大小转换为线圈偏转角度的大小,其物理原理是。
24.想想看,初中物理学习中,你在研究什么问题时用到过转换法?请举一例并说明你的研究过程。(第23、24题的研究实例除外)
