3.如图所示,固定的倾角为37的粗糙斜面上放置一长方体物块,现用一大小等于物块重力,方向与斜面成37^“角斜向下的推力推动物块(力的作用线在斜面上的投影与斜面底边平平行),物块在斜面上恰好做匀速运动。则物块与斜面间的动摩擦因数为(37^=0.6,37^=0.8)A.34C.56D.

7.如图甲所示的电路中,原线圈与滑动变阻器串联后接在电压的有效值恒定的交流电源上,理想变压器原、副线圈的匝数比为10:1,R1=10,R2为滑动变阻器,电压表和电流表均为理想电表。当R2=R0时,电流表的示数随时间t变化的正弦曲线如图乙所示。下列说法正确的是()

(5)任何实验测量都存在误差,下列关于误差的说法中正确的是(填正确答案标号)。A.用螺旋测微器测量金属丝直径时,由读数引起的误差属于系统误差B.电流表A1和改装后电流表A2的内阻对Rx测量值无影响C.由所选取电阻箱R1的最小刻度引起的误差属于偶然误差D.若定值电阻R0所标阻值不准,不会影响金属丝电阻率的测量值
