The masses and weigh le:*87yygvui (z pdgw* ( jx8dts of different objects a qthtf)6br 5kmezfe 6)bm)g s.p5mm2)re independently measured. The graph is a plot of weight versus mass that includes e m e2)f56fmsth z6 m 5).kgbtqprm)b)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 ibyj )myxm8yki4b56f:6e z b+ go through (0,0) as mass and weight are directly proportional. However it does not, so there is a syste ybfx66j+kb85 imbm4z i) eyy:matic 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.
