The masses and weigh w;k9 (mk 79 kxm3)ss0yxnnwlfts f;6djvvfg6o6 of different objects are independently measured. The graph is a plot of weight versus mass that include dv6fvfj6;go6 s 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 line3v pd m0r697 7xajslzxdc m-1e should, theoretically go through (0,0) as mass and weight are directly proportional. However it does not, so there is a systematic er-permm7xd97ad13zvj lx6s 0cror. On the other hand the points all sit on a straight line which shows there is no appreciable random error. Hence C is correct.
