DNA is an evolutionary clock that's extremely useful in our lives because it mutates. The mutations that occur in our DNA causes the organisms to diverge evolutionarily from one another, providing us our natural clock in the timeline of evolution.
Answer:
The answer is
<h2>5 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and it's net force can be found by using the formula

From the question
force = 60 N
mass = 12 kg
So we have

We have the final answer as
<h3>5 m/s²</h3>
Hope this helps you
If you mean which of the two is denser, then you want the oceanic crust.
