The masses and weights of differ +n ;vbr: * shl2*zoruwe o*ku-1qse) fs+v ap(u+snu 8 vnt objects are independently measured. The graph is a plot of weight versus mass v1*ueupnoss f+ (+k- 8 sav)uqthat 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 should9w819wr f ikz3 o mw0 (fuoovig5vw6h7, theoretically go through (0,0) as mass and weight are directly proportional. However it does not, so there is ao7v9 (0m 1uow 5g3vfiokwiw6wf z9hr8 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.
