What did Bohr’s model of the atom include that Rutherford’s model did not have?

Answer:
As we know that as per Rutherford's model we have will have an model in which he said that there is a small center at which whole positive charge is concentrated in an atom and all electrons will revolve around that positive charge.
So here in Rutherford's model he describe about the nucleus of the atom.
Now in Bohr's model he said that the orbit in which all electrons revolve around the nucleus is known as stationary orbit and there is no energy loss in that orbit when electron revolves in it.
So here we can say that in Bohr's model he included the part of stationary orbit which is not included in Rutherford's model.
As we can say that in Bohr's model the energy of electron is constant when it revolves in its stationary orbit and when electron changes its orbit then energy will be released in form of photons.
For stationary orbit the angular momentum of the electron must be integral multiple of
so it is

Answer:
The ratio is KE : TM = 0.75
Explanation:
from the question we are told that
The displacement of a mass on a spring in simple harmonic motion is A/2 from the equilibrium position
Generally the total mechanical energy of the mass is mathematically represented as
Here k is the spring constant , A is the total displacement of the the mass from maximum compression to maximum extension of the spring
Generally this total mechanical energy is mathematically represented as
=>
Here the potential energy of the mass is mathematically represented as
Here x is the displacement of the mass from maximum compression or extension of the spring to equilibrium position and the value is
So
So
=>
=>
So the ratio of is mathematically represented as
=>
Answer:
Option C
Explanation:
Kinetic energy is the energy that the body possesses by virtue of its motion.
The formula for Kinetic energy is given by
Using this formula let us find kinetic energy for the bodies given and find out which is the greatest
A) KE =
B) KE =
C) KE =
D) KE =
Comparing these we find that 9mv^2 is the highest.
Hence option C is the answer.
