I just got this question not to long ago but to answer your question the primary function of the respiratory system is to exchange oxygen<span> and carbon dioxide. Inhaled </span>oxygen enters the lungs<span> and reaches the alveoli. </span>Oxygen<span> passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.</span>
Something that is not magnetic
E=hf
E=6.626e-34[Js]•1500e3[Hz]=9.939e-28[J]
For eV divide this by electron charge
9.939e-28[J]/1.6022e-19[C/e]=
6.203e-9eV
Answer:
D. absolute magnitude and apparent magnitude
Explanation:
At the top of the the ball's trajectory, there is only the horizontal component of the initial velocity, which is 
so the kinetic energy of the ball at this point is
![\;\;\;\;\;= \frac{1}{2}(0.15\:\text{kg})[(40\:\text{m/s})\cos30]^2](https://tex.z-dn.net/?f=%5C%3B%5C%3B%5C%3B%5C%3B%5C%3B%3D%20%5Cfrac%7B1%7D%7B2%7D%280.15%5C%3A%5Ctext%7Bkg%7D%29%5B%2840%5C%3A%5Ctext%7Bm%2Fs%7D%29%5Ccos30%5D%5E2)
