The masses and weights o ol-z4 ),cwss9hrrl ) of different objects are b+lg8w/-d gu t independently measured. The graph is a pl d -lu btg+gw8/ot of weight versus mass that includes error 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 mas r24js0(c qcfks and weight are directly proportional. Hk (qsrf4cc0j2 owever 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.
