5. What is the net force in the following two situations? Situation &
Situation B
norm= 3 N
Fnorm =
= 3N
Ffrict= 5 N
= 5 N
Fapp
Ffrict= 5 N
Fgray= 3 N
Foray= 3 N

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.
