Acar advertisement states that a certain car can accelerate from rest to 20 m/s in 7 seconds. how far does this car go? what is the car’s acceleration?

It's acceleration a  =  20 / 7 = 2.857 ms^-2.

Using  the equation of motion under constant acceleration:

Distance travelled  = 1/2 * a * t^2

= 1/2 * 2.857 * 7^2

= 70.00 m  (to the nearest hundredth).

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

i'm on my way to history not a mistory.
