The masses and weight p59zgb 9cmf x3u fd*s6s 4r y5m9b0elvk t1ms,yqn0kkzu3uh v8/ ,) shzof different objects are independently measured. The graph is a plot of weight versus mass t usry t0 3hblkz,,9 )mz qvs1ueh vyk/ 84k5mn0hat 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 mass and wei1jt-n cx9dmd9, r* kofght are directly 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 *ct,9f1roj m nd-kdx9C is correct.
