Answer:
f(-9) = 184
Explanation:
f(x)=3x²+5x-14
f(-9)= 3(-9)² +5(-9)-14 Order of Operations : Exponents
= 3(81)+5(-9)-14
= 243+5(-9)-14
= 243-45-14
= 198-14
f(-9)= 184
Hope this helps :)
Answer:Developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete- Niels Bohr
Discovery of energy quanta made him the originator of quantum theory -Max Plank
Formulated the wave equation; stationary and time-dependent Schrödinger equation- Erwin Schrödinger
Best known to the general public for his "mass–energy equivalence formula" ; E = mc^2-B Albert Einstein
Postulated the wave nature of electrons and suggested that all matter has wave properties- Louis de Broglie
Explanation:
All the names mentioned above contributed towards the development of the wave mechanical model of the atom. Their names were matched with their contributions as required by the question.
So I am assuming that by "the following," you mean in general terms.
The shortest wavelength of the spectrum is the Gamma Ray waves, they are 400nm and are the most deadly, because of how often and frequent they are able to vibrate. Shorter the wavelength the more active.
So the list from "shortest," to "longest," is,
Gamma Ray, X-Ray, Ultraviolet, Visible, Infrared, Microwave, and Radio wavelengths.
In the spectrum, Radio has the longest and furthest traveling waves. This means that they are not harmful and that they can travel extreme distances.
Hope this helps!
Answer:
<h3>Uniform polarization of the heart membranes</h3>
Explanation:
I<span>f you have studied enzymes its a similar concept. Cells have proteins on the surface of their cell which hormones bind to (called receptors) The receptor must be a complimentary shape to the hormone for it to bind. Only target cells have the receptor with the complimentary shape so only these cells will be affected.</span>
