The masses and weights of diffe w82pojp3wy *w8qoee *cvg o( 1rent objects are 10fei 4c:vhp0 x0dxl t independently measured. The graph is a plot of weight versus mass that inc ch :ft 4lp10x0ev0xd iludes 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 we 14:;wretjkgo ight 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 jg rewt:4o1 k;C is correct.
