The masses and weights of differen 6v4ljyeap9;m;j n.z qt objects are inde hwj;qie2wzlu cjhe 64 gq2 5+0pendently measured. The graph is a plot of weight versus mass that includes error z5eg+hiqu j0q ww 2hl2cej46 ; bars.  What do these experimental results suggest?
A. The weight of an object is inversely proportional to its mass.
B. The measurements show a significant random error but small systematic error.
C. The measurements show a significant systematic error but small random error.
D. There is no correlation between the weights and the masses of the objects.
参考答案: C
本题详细解析:
We know that the line should, theoretically go through (0,0) as ma2y-gisqkul8 7 ss and weight are direcku yi2l8- sq7gtly proportional. However it does not, so there is a systematic error. On the other hand the points all sit on a straight line which shows there is no appreciable random error. Hence C is correct.
