Answer:
The value 
Explanation:
From the question we are told that
The weight of the sky diver is 
The magnitude of the drag force is 
The mass of the sky diver is 
Generally the net force acting on the sky diver is mathematically represented as

Hence the acceleration of the sky diver is mathematically represented as

=> 
=>

Answer
Together with glycolysis, The Krebs cycle, and the electron transport chain release about 36 molecules of ATP per molecule of glucose.The Krebs cycle uses the two molecules of pyruvic acid formed in glycolysis and yields high-energy molecules of NADH and flavin adenine dinucleotide (FADH2), as well as some ATP. The electron transport chain forms a proton gradient across the inner mitochondrial membrane, which drives the synthesis of ATP
I don't really know the answer but maybe north pole and south pole?
