At present I am still uncertain about my academic education (that is, which subject to study). If I were to decide on chemistry, would you commend organic or inorganic chemistry? Why? How are the two different when it comes to studying them?
Answers are appreciated.
Actually, I think plant only use the sunlight as an energy source to produce glucose and oxygen from water vapor and carbon dioxide.
CO_2(g)+H_2O(g)+energy\rightarrow C_6H_{12}O_6(s)+O_2(g)
It is true that energy and mass (matter) has a distict relationship \left(E=mc^2\right), but the...
Isn't this just the reflection law, \theta_{inbound}=\theta_{outbound} with theta measured on the tangent (plane) of the collision surface at the collision point?
I solved the integral to
\int \frac{dv}{A-Bv-Cv^2}=-\frac{2\tan^{-1}\left(\frac{B+2Cv}{\sqrt{-B^2-4AC}}\right)}{\sqrt{-B^2-4AC}}, so then t=-\frac{2\tan^{-1}\left(\frac{B+2Cv}{\sqrt{-B^2-4AC}}\right)}{\sqrt{-B^2-4AC}}
Working with this, I get that...
This is not a homework problem, just an idea I had.
If we have a sphere which is being accelerated in space by a force \vec{F} and we take the drag into account, what would the displacement be after t seconds? If the drag force is \vec{D}=-c_1v-c_2v^2, then the acceleration would be...
