Answer and Explanation:
This can be explained as in Rutherford's model of atom the electrons orbits the nucleus which means that they will travel around the nucleus with some velocity and hence radiate electromagnetic waves which results in the loss of energy due to which the electron keeps coming closer and eventually falls into the nucleus.
But Bohr came up with a better explanation as according to the Bohr's atomic model, electrons stay fixed in orbit with certain energy in different shells around the nucleus and can only jump from an energy level to another if that specific amount of energy is supplied to it.
This model is based on the quantization of energy thus giving an explanation why electrons do not fall into the nucleus of an atom.
Answer:
Explanation:
According to Gausses theorem, electric flux coming out of charge on all sides q is equal to
q / ε₀
q is charge , ε₀ is permittivity of air whose value is given by
8.85 x 10⁻¹²; q = 21.2 x 10⁻⁹ C
Putting the values we get
FLUX =
2.4 x 10³ Nm²/C
Answer:4s^-1
Explanation:Tangential Acceleration=v^2/r=(20)²/100=400/100
Answer:
when the radius is halved, F becomes 4 times
Explanation:
<u><em>The formula is given by</em></u>
<u><em>When r is halved:</em></u>
=>
=>
<u><em>This means when the radius is halved, F becomes 4 times</em></u>
Experimental Evidence.
Scientists conduct experiments or observations to gather evidence that either support or disprove a given hypothesis. Hence, all the scientific explanations are based on this body of observations.
