A car has a mass of 10006z *n/ae8gpw hkg. A mouse has a mass of 10g. What is the order of mqi 3*w*po bt,kagnitude of the ratio between the mas ,**qki3w btpos of the car to that of the mouse?
A. -5
B. 5
C. $10^{-5}$
D. 100000
参考答案: B
本题详细解析:
The mass of the car must be converted to grams first, by9j.p.i /-fr; 2o:a.qw uuxq;asus 3af4bma tk multiplying by 1000 . The ratio is the mass .i-f/j.4s;u2w;am q:xoktf aa3 bua.su p9rq of the car divided by the mass of the mouse: $$ \frac{1000 \times 1000}{10}=100000 $$ As $100000=10^5$, the order of magnitude is 5 .
