Positive - Friction allows us to create heat in a desperate situation, like being lost in the woods. If we didn't have friction, we would probably freeze to death.
Negative - Friction can also cause unwanted fires, such as forest fires. If friction didn't exist, we wouldn't have these.
There is no net vertical force.
The 20N upward is exactly balanced by the 20N downward.
There IS a net horizontal force.
(22N to the right) + (14N to the left) = 8 N to the right.
The net force acting on this object is 8 newtons to the right.
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
Answer:
λ = h/p
<u>
</u>
This energy is equivalent to E=150.44eV
Explanation:
<u>de Broglie Equation:</u>
λ = h/p
h=6.63×10-34 m2 kg / s Planck's constant
so: p=h/λ
On the other hand, an atomic distance, an angstrom, is equal:
, λ should be similar to this distance.
<u>Kinetics Energy of a electron, m=9.11×10−31 kg</u>
<u>
</u>
<u>Number of volts needed to accelerate that electron from rest to this energy:</u>
So, this energy is equivalent to E=150.44eV
This high-voltage device is called: particles accelerator
