The masses and weights o tyrt: ;g5s+oio;qvgb:h8t t; .+g bzz f different objects are indep tby0- a1s7kgncm d3yf;tcvbd ;., t; kendently measured. The graph is a plot of weight versu y7-0y,gts;;v.d1c3; dt cbbkka nf mt s mass that 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 go through (0,0) as mass and o gzejr dn q/x.99isdvdk*1:: 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. Hen.k9oz s v :/djd*eg xi91nrd:qce C is correct.
