In order to answer these questions, we need to know the charges on
the electron and proton, and then we need to know the electron's mass.
I'm beginning to get the creepy feeling that, in return for the generous
5 points, you also want me to go and look these up so I can use them
in calculations ... go and collect my own straw to make the bricks with,
as it were.
Ok, Rameses:
Elementary charge . . . . . 1.6 x 10⁻¹⁹ coulomb
negative on the electron
plussitive on the proton
Electron rest-mass . . . . . 9.11 x 10⁻³¹ kg
a). The force between two charges is
F = (9 x 10⁹) Q₁ Q₂ / R²
= (9 x 10⁹ m/farad) (-1.6 x 10⁻¹⁹C) (1.6 x 10⁻¹⁹C) / (5.35 x 10⁻¹¹m)²
= ( -2.304 x 10⁻²⁸) / (5.35 x 10⁻¹¹)²
= 8.05 x 10⁻⁸ Newton .
b). Centripetal acceleration =
v² / r .
A = (2.03 x 10⁶)² / (5.35 x 10⁻¹¹)
= 7.7 x 10²² m/s² .
That's an enormous acceleration ... about 7.85 x 10²¹ G's !
More than enough to cause the poor electron to lose its lunch.
It would be so easy to check this work of mine ...
First I calculated the force, then I calculated the centripetal acceleration.
I didn't use either answer to find the other one, and I didn't use " F = MA "
either.
I could just take the ' F ' that I found, and the 'A' that I found, and the
electron mass that I looked up, and mash the numbers together to see
whether F = M A .
I'm going to leave that step for you. Good luck !
Answer:
a. its constitution and mixed government.
Explanation:
Polybius tell us about the Roman mixed constitution as a fundamental in the Roman victory and the Carthaginian defeat in the Punic war, conceiving the mixed constitution as the best, since this constitution was at its peak, which implies that among the elements of the constitution, the aristocratic component was the dominant one.
Explanation:
Polar molecules are the molecules with net dipole due to presence of partial positive charges and partial negative charges. For example of water molecule.
Water molecule is made up of the one oxygen atom and 2 hydrogen atom. There two lone pairs on the oxygen atom which repel both the (O-H) bond pairs away from them.Also oxygen being electronegative attracts the shared pair of electrons towards itself. Due to this the net dipole generates in a water molecule directing towards the lone pairs of the oxygen atom.Hence this makes the water molecule polar
Non Polar molecules are the molecules in which equal sharing of electrons is present that is no net dipole is present. Atom with equal electronegativites have forms polar molecules
Carbon dioxide molecule is a made up two oxygen atoms and 1 carbon atom. Since, there are two electronegative atoms which will attract electrons bond pairs towards itself equally from the both sides which will cancels out the each other dipole resulting in no net dipole in the molecule which makes it non polar molecule.
