9.随着汽车不断普及,对于安全驾驶的要求越来越高路考是驾照考试的指定科目,路考中有一项是定点停车,路考过程中某辆车运动的v-t图像如图所示,下列说法正确的是A.1s~2s内,汽车匀速行驶B.2s~4s内,汽车的加速度大小为/sC.汽车在0~1s内的加速度小于2s~4s内的加速度0-2=2×2XD.汽车在0~1s内的运动方向与2s~4s内的运动方向相反x2

5.如图甲所示,在xOy平面内存在平行于纸面的匀强电场,现有一个质量为m、,电量为+q的带电微粒,在外力F的作用下,=0时刻以一定初速度从x轴上的a点开始绕O点沿图中虚线逆时针做匀速圆周运动,,Oa=R,ab为圆的一条直径,不计重力,测得该带电微粒所处位置的电势随时间的变化图像如图乙所示.下列说法正确的是A.微粒在3t1时所受变力F可能达最大值B.B.电场强度的大小为1+22R,,方向与x轴正方向成向上Um=-22(1+2)C.b点与a点的电势差UD.圆周运动的过程中变力F的最大值为F=m^216r1R+q1+22R

Rx(2)为了尽可能精确测量R的阻值,该同学设计了如图乙所示的电路,所选实验器材均符合S1,S2a,实验要求.闭合S,将S接a,调节滑动变阻器滑片P到适当位置并保持不变,此时电压表示数为U1,电流表示数为I1;S2S接b,电压表示数为U2,电流表示数为I,则待测U2,I2,则待测电阻的阻值为RRx=-2&2(用测量量的字母符号表示),实验计算得到的R,值与真Rx实值相比(选填“偏大”偏小”或“相等”).
