13.(10分)导热性能良好的汽缸内壁顶部有一固定卡环,卡环到汽缸底部高度为20cm,一个质量为1kg的活塞将汽缸内气体封闭,汽缸内壁光滑,活塞与汽缸内壁气密性良好,静止时,活塞与卡环接触,已知大气压强为110^5Pa,环境温度为300K,当环境温度降为280K时,卡环对活塞的压力刚好为零,重力加速度取210m/s^2,活塞的截面积为5cm^2,不计活塞的厚度,求:(1)开始时,汽缸内气体的压强;9&7×105(2)当环境温度为280K时,在活塞上放一个质量为2kg的重物,当活塞重新稳定时,活塞离缸底的距离。

(3)为为减R8的测量误差,操作作如下:在(1)中粗测出补回RB来.具体的数值可以通过估算得出,实际操作如下:在(1)中粗测出R后,再把R先增加到R1先来.具体体的数值可以通过先增曾加到数值值],再调节R2[用第(1)问中的有关条件求得具体数值],再调节R使电流表.用这时R的用第(1)问中的一值表示R的测量值,如此多次补偿即可使误差尽量得以减小.R2R836km/h,

2.指南针是我国古代四大发明之一。关于指南针,下列说法正确的是A.指南针可以仅具有一个磁极B.指南针的指向不会受到附近磁铁的干扰C.可根据指南针的S极指向地理北极来辨别方向D.在指南针正上方附近沿指针方向放置一直导线,导线通电时指南针会偏转
