A 900 kg car accelerates 2 m/s2 to the right. What is the net force acting on the car?

1800 N to the left
450 N to the right
450 N to the left
1800 N to the right

F = m a and acceleration is in the same direction as the net force.

The net force on the car is 1800 N to the right.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

this could be newton#'s law of cooling. the cooling curve is exponential
