A 30 kg object has 3 forces acting on it - one 40 N force to the right, one 20 N force to the right, and one 30 N force to the left. What is the net force on the object?

Fnet=F1+F2-F3=40+20-30=60-30=30N

F=ma

30N=30a

a=30/30

a=1m/s^2

Believe me , biology is another thing.

significant amounts of nitrogen oxides, carbon monoxide, and other pollution

explanation:

passenger vehicles are a major pollution contributor, producing significant amounts of nitrogen oxides, carbon monoxide, and other pollution. in 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.
