Explanation: An ignition interlock device is an onboard breathalyzer test. The driver has to blow into it to prove that they are below the legal limit and able to drive. The car will not start unless the mouthpiece is blown into and the driver is sober.

explanation:

newton's third law, for every action there is an equal and opposite reaction.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
