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:
Explanation:
Arrangements of cells, when two or more cells are connected together they form what is called a battery
There are two ways cells can be connected
1. Parallel
2. Series
Find attached a sketch of serial arrangement
Answer:
a)
b)
c)
Explanation:
From the question we are told that
Mass of soft rubber
Spring compression
Stiffness constant
Ball Distance
Frictional force
a)Generally the equation for motion of the second ball according to Newton's law is given by
b)Generally for speed to be at maximum spring force must equal frictional force
At distance
Therefore
Ball is at maximum speed at
c)Generally maximum velocity is represented mathematically as
Btw only someone who is nice will answer tour question. You can't expect for explanition when the question is only worth 5 points. Not trying to be mean sorry if i am being mean
The answer is C adding more mass(Tape) to the balls(No homo) would increase the gravitational pull.
