1.小明在医院看到一种输液警报器（如图甲），当管内药液流完时，电铃发声，报警器内部有一可变电阻，当输液管内有液体时，电阻大，无液体时，电阻小，电路如图乙所示，则当闭合开关报警器工作，输完药液时，电铃响的原因是：电铃两端电压{#blank#}1{#/blank#}，电铃正常工作．
2.小明在医院看到一种输液警报器（如图甲），当管内药液流完时，电铃发声，报警器内部有一可变电阻，当输液管内有液体时，电阻大，无液体时，电阻小，电路如图乙所示，则当闭合开关报警器工作，输完药液时，电铃响的原因是：电铃两端电压{#blank#}1{#/blank#}，电铃正常工作．
3.实验桌上有两个完全相同的烧瓶，烧瓶内装有质量相等的煤油、型号相同的温度计和阻值不等且不变的电阻丝R，如图所示．另外，还有满足实验要求的电源、滑动变阻器和开关各一个，电流表和停表各一块，导线若干．请利用上述实验器材，设计一个实验证明：“保持电流值不变，在相同时间内，电流通过电阻产生的热量多少与电阻大小有关”．实验设计中可用煤油升高的温度△t的大小表示电流通过电阻丝R产生热量的多少．
7.阅读短文，回答问题．
茶杯的变迁
在古老的欧洲流行一种陶瓷茶杯，叫梨形杯（如图所示），它较大的杯口使茶水有令人满意的变凉效果．下部球形设计茶杯有较小的表面积和较大的容量，这种设计又能使茶水保温很长时间，让你长时间谈话时可以细品热茶．梨形杯在欧洲沿用数百年后，被廉价的圆柱形玻璃杯所代替，因为玻璃把手的发明，使玻璃杯得以更加方便地使用．
8.某工人使用如图甲所示的滑轮组匀速提升浸没在水中的实心物体A，拉力的功率随时间的变化如图乙所示，已知动滑轮的重力为60N，物体匀速上升的速度始终为1m/s．（不计绳重，摩擦及阻力，ρ水=1×103kg/m3，g=10N/kg）
