The masses and weights of different objects are i k*ljln3f f: -cpwkc(b149 nbandependently meas ne98065j/ zio8t4vs mw lhaxnured. The graph is a plot of weight versus mass that includes er v5oxaj s06nm8 9thn zl8e 4/iwror 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 ma t vj akyz3*7zbr*f5nbyl+k6 .ss 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. ykarv z3z6*n+fljt 7.5bb y*k Hence C is correct.
