Such an instrument could be called the Laser Scan Micrometer.
He wanted an instrument he could hoist.
A ruler is an example of an instrument that can be used to measure relatively small linear distances, though it could not measure all three at once.
One could use a ruler.
The instrument you would use could be a beaker or a graduated cylinder.
a bathroom scale
A stopwatch could be used.
An altimeter.
seismograph is one instrument that could measure earthquakes and volcanoes etc but seismograph is many times use at earthquake!
The most direct way to measure the angle of a hill would be to use a clinomiter. You could also use a level and staff.
Scientist use physics for all sorts of things. Scientist can use Newtons and other gravity-related laws to work out the trajectory of a crashing satellite. If scientist wanted to, he could look use molecular physics to predict how chemicals will react. Scientist is a pretty cool guy.
We could use a laboratory scale to measure a mole of solid material. A mole represents Avogadro's number of atoms or molecules of the solid material. Table salt, sodium chloride, for instance has a weight of 58.44277 grams per mole. The scale in the chemistry lab would be the instrument to use to measure that and to measure out a mole of most other solids.
