It didn't let me finish writing this.
For number 1, option D is 3.0 x 10-10 m.
For that question I got B.
2. A student wishes to make a measurement of the road distance from his dormitory to the physics building of his university. she uses her car's trip odometer, which measures distance only in units of a tenth of a mile. She makes one trip, and the odometer reads 0.3 mi. What can she say is the distance ?
A. 0.3 mile
B. 0.1 mile
C. 0.2 mile
D. 0.4 mile
I put A but it seems too simple.
3.In the above problem to how many significant figures can she claim she knows the distance?
I put C.
4. In the same problem above if she has to know the distance to the physics department to the next significant figure how many round trips to the department should she take ?
I'm stuck on this one.
I'm just going to post this again since it keeps cutting my answers off.
correct on 1.
