At an event demonstrating old cannons, four different cannons are fired. The cannon balls used in the cannons are spherical lead balls with different masses. The cannons are fred vertically and the cannonbals are fred from them at exactly the same speed with exactly the same amount of force.
According to Newton's 2nd Law of motion, which cannon ball will reach the greatest height? (DOK 2, AKS 8b)
O A The ball in cannon D
B. The ball in cannon A
C. The ball in cannon B.
D. The ball in cannon C

I think the answer is A becasue if there spread vertically then they must not have the same mass or speed.

Explanation:

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
