The sun is made mostly up of Hydrogen.
Answer:
Yes, the frequency of light emitted is a property of the difference between the levels of energy of its electrons.
Explanation:
Neon atom is a noble gas which glows when its electrons de-excites after absorbing energy.
Niels Bohr postulated that the energy level in all atoms are quantized, thus electrons do not exist in-between two levels. When electrons in the Neon atom are excited, this increase in energy causes them to jump to a higher energy levels. On de-excitation, the electrons drops to their initial level releasing the absorbed energy in the form of a photon.
The photon emitted has a frequency that is directly proportional to the energy change in the electron.
The concept required to perform this exercise is given by the coulomb law.
The force expressed according to this law is given by
Where,
q = charges of the objects
r= distance/radius
Our values are previously given, so
Replacing,
The force acting on the block are given by,
Therefore the box is accelerated upward.
Answer:
Fog forms in a valley
Explanation: that’s the only reasonable response
