（1）用已调零且选择旋钮指向欧姆挡“×10”位置的多用电表测某电阻阻值，根据图1所示的表盘，被测电阻阻值为______Ω．若将该表选择旋钮置于1mA挡测电流，表盘仍如图1所示，则被测电流为______mA．

（2）某同学用图2所示装置测量重力加速度g，所用交流电频率为50Hz．在所选纸带上取某点为0号计数点，然后每3个点取一个计数点，所有测量数据及其标记符号如图3所示．

该同学用两种方法处理数据（T为相邻两计数点的时间间隔）：

方法A：由g₁=

S2-S1

T2

，g₂=

S3-S2

T2

，…，g₅=

S6-S5

T2

，取平均值

.

g

=8.667m/s²；

方法B：由g₁=

S4-S1

3T2

，g₂=

S5-S2

3T2

，g₃=

S6-S3

3T2

，取平均值

.

g

=8.673m/s²．

从数据处理方法看，在S₁、S₂、S₃、S₄、S₅、S₆中，对实验结果起作用的，方法A中有______；方法B中有______．因此，选择方法______（A或B）更合理，这样可以减少实验的______（系统或偶然）误差．本实验误差的主要来源有______（试举出两条）．
