Micro-meter screw gauge:
Has two scales, main scale is in the shaft, and the fractional scale is on the rotating barrel, the fractional scale has 50 divisions

Question 3

Density def

Answer 3

The ratio of mass to volume for a substance

Density = mass / volume

Question 4

Period (of time)

Answer 4

The time for one swing of a pendulum (from left to right and back again)

Question 5
