Answer: one brain... humans have one brain
Explanation: humans have many parts of the brain but they only have one brain there are left brain right brain people. Right brain tends to me more creative and left brain is more logical but its is all still the same brain you just use different parts of the brain at one time
Your answer is D- high energy and short wavelengths : )
Answer: As the "wind" pushes the blades and makes them to spin, kinda like an inverse process of how a fan works (where in the fan you impunt energy to make the blades move and generate wind, and in this case the wind makes the blades move to generate electricity), and this movement of the blades creates work that is transformed into electric energy.
Without the wind, you can not generate work in the blades, and then electric energy can not be generated, so you need this source to "push" and impulse torque in the blades.
Answer:
c.Therefore, we can say that the energy difference between adjacent orbit radii decreases with increasing values of the principal quantum number.
Explanation:
For the adjacent orbits or orbits that are one above the other
change in energy is given by
ΔE =![13.6 [1/(n)^2 - 1/(n+1)^2 ]](https://tex.z-dn.net/?f=13.6%20%5B1%2F%28n%29%5E2%20-%201%2F%28n%2B1%29%5E2%20%5D)
where n= orbital number
so ,
now , if n value is increased,
value [ 1/(n)^2 - 1/(n+1)^2 ] will go on decreasing by clear observation as n is in the denominator
Therefore, The energy difference between adjacent orbit radii decreases with increasing values of the principal quantum number.
