the force between the electron and the proton.
a) Use F = k * q1 * q2 / d²
where k = 8.99e9 N·m²/C²
and q1 = -1.602e-19 C (electron)
and q2 = 1.602e-19 C (proton)
and d = distance between point charges = 0.53e-10 m
The negative result indicates "attraction".
the radial acceleration of the electron.
b) Here, just use F = ma
where F was found above, and
m = mass of electron = 9.11e-31kg, if memory serves
a = radial acceleration
the speed of the electron.
c) Now use a = v² / r
where a was found above
and r was given
<span> the period of the circular motion.</span>
d) period T = 2π / ω = 2πr / v
where v was found above
and r was given
What's your question BTW?
Can't understand what u have typed
Answer: warmer because its an exothermic reaction.
Explanation: the passage states as the products form thermal energy is absorbed thermal means heat also carbon dioxide creates bubbles
I think that it is D because the higher the molecular mass, the higher it's boiling point. I hope that helped:) Bye!
In an orderly, repeating, three-dimensional pattern called a crystal lattice.
