Give the length of the line segments in the requested units. ac = 30 mm 3 mm 0.3 mm cf = 0.02 mm 20.2 mm 20 mm eg = 10 m 0.1 m 10.01 m

1 cm = 10 mm

AC = 3 cm = 3 * 10 mm = 30 mm

CF = 2 cm = 2 * 10 mm = 20 mm

1 m = 100 cm => 1 cm = 0,01 m

EG = AB = 10 cm = 10 * 0,01 m = 0,1 m

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
