A ruler has millimetre marks. What is the usual reading uncertainty for a single reading?
± 0.1 mm
± 1 cm
± 0.5 mm
± 5 mm
2.
A voltmeter scale is marked every 0.5 V. The needle is a quarter of the way from 2.0 V to 2.5 V. The best reading is:
2.0 V
2.25 V

3.
Why does a mirrored scale on a meter help?
It removes parallax when the needle and its image coincide
It amplifies the signal
It reduces the current
It increases the range
4.

0 cm3
1 cm3
0.5 cm3
2 cm3
5.
