The masses and weights of differe l5mdbt 11dmst;67 h jpnt object c i8vuwu b4y+x*g1+uos are independently measured. The graph is a plot of weight versus mass that includes error b y8 uwb4uco u+i+*1 xgvars.  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 (0,06stm7 cp;5 9r.jaq dec) 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 therj 6 .ad7c;tmcp5e9sq re is no appreciable random error. Hence C is correct.
