What is the metric unit used to measure length? mass? volume? temperature? list one tool used to measure each type of measurement

Length

The metric unit used to measure length in International System (SI) is meter and it is represented by letter m.

Length can be measured by a metric scale.

Mass

The metric unit used to measure Mass in International System (SI) is Kilograms and it is represented by letter Kg.

Mass can be measured by an instrument called Balance.

Volume

The metric unit used to measure Volume in International System (SI) is Liter and it is represented by letter l.

Volume can be measured by a container called graduated cylinder.

Temperature

The metric unit used to measure Temperature in International System (SI) is Kelvin and it is represented by letter K.

Temprature is measured by most common divice called thermometer.

wire in brush may conduct electricity from cell to drill and vice versa electrc shock possible

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
