an object is shot vertically upward into the air with an initial velocity of 20 m/s? which of the following correctly describes the velocity and acceleration of the object after 4seconds?

Answer is (C)

Explanation:

For acceleration

• If the motion is vertically, then acceleration is 9.8 m/s²

» Upward motion, acceleration is negative (-9.8)

» Downward motion, acceleration is positive (+9.8)

For velocity

what is the question?

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