Does wind move in a straight line like it shows in this picture? .

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.

i think the answer is a and b

i wish you luck

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.
