The masses and weights of diffe 6lwf q7 oc 7+ 37lml da)xbwenwk)-dz:rent obje xuhs)zyi97wl-lm 6c sqj24+q cts are independently measured. The graph is a plot of weight versus mass tha 2m-s qhc7 4lwz si+jyuxql)69t 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 .- w1v8co 4,gfqgpekcgo through (0,0) as mass and weight 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 C ispq.1ck4 w,g veof-8cg correct.
