1. Length and Time

To find the volume of an irregular object: 1) Take a [blank_start]cylinder[blank_end] and fill it with some [blank_start]water[blank_end]. 2) Place the [blank_start]object[blank_end] into the [blank_start]cylinder[blank_end]. 3) (Volume of [blank_start]object[blank_end] + [blank_start]water[blank_end]) - (Volume of [blank_start]water[blank_end]) = Volume of [blank_start]object[blank_end]

Label the parts of the micrometer screw gauge:

The ratchet is provided to [blank_start]avoid[blank_end] [blank_start]excessive[blank_end] [blank_start]pressure[blank_end] on the [blank_start]wire[blank_end]. It [blank_start]prevents[blank_end] the [blank_start]spindle[blank_end] from further [blank_start]movement[blank_end] - [blank_start]squashing[blank_end] the [blank_start]wire[blank_end].

When measuring with a micrometer screw gauge, the [blank_start]diameter[blank_end] of the wire is the sum of the [blank_start]main[blank_end] [blank_start]scale[blank_end] and the [blank_start]rotating[blank_end] [blank_start]scale[blank_end].

To find the amount of time it takes a pendulum to make a spin, time ~[blank_start]25[blank_end] [blank_start]circles[blank_end] and then [blank_start]divide[blank_end] by the [blank_start]same[blank_end] [blank_start]number[blank_end] as the [blank_start]number[blank_end] of [blank_start]circles[blank_end].
