The radius of a nucleus of hydrogen is approximately
, while we can use the Borh radius as the distance of an electron from the nucleus in a hydrogen atom:
The radius of a dime is approximately
: if we assume that the radius of the nucleus is exactly this value, then we can find how far is the electron by using the proportion
from which we find
So, if the nucleus had the size of a dime, we would find the electron approximately 500 meters away.
Answer:
<h2>1.4 m/s</h2>
Explanation:
The velocity can be found by using the formula
k is the kinetic energy
m is the mass
From the question we have
We have the final answer as
<h3>1.4 m/s</h3>
Hope this helps you

Answer:
A board is hung from two springs, as shown in the figure above, with the board in equilibrium. Each spring has a spring constant of 10,000 N/m. How far will each spring stretch when a person of mass 50 kg sits on the board and the board again comes to equilibrium?
