The masses and weights of d u:q8oizo z8vhoib 6 0(iffe t3ir ln 5gh8o ;a/3xsnrent objects are independently measured. The graph is a plot of weight versus mass that includes err /in 8rgs a ox;5nlh3t3or 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 mass and weig:b+y- bj7 dytv4. s-d xwqfij :j7m6soht are directly proportional. However it does not, so there is a systematic error. On the other hand the points all sit on a qd :sj.j i: ov7wb4x-76 -ymyt+ fsdjbstraight line which shows there is no appreciable random error. Hence C is correct.
