Answer:
the photons (quanta of light) collide with the electrons, these electrons have to overcome the threshold energy that is the energy of union with the metal, and the energy that remains is converted to kinetic energy.
K = E - Ф
Explanation:
The photoelectric effect is the emission of electrons from the surface of a metal.
This was correctly explained by Einstein, in his explanation the energy of the photons (quanta of light) collide with the electrons, these electrons have to overcome the threshold energy that is the energy of union with the metal, and the energy that remains is converted to kinetic energy.
E = hf
E = K + Ф
K = E - Ф
The energy of the photons is given by the Planck relation E = hf and according to Einstein the number of joints must be added
E = n hf
Therefore, depending on the value of this energy, the emitted electrons can have energy from zero onwards.
I think so it ans wold be d.because if the source approaches the observer more and more wavefront will pass and it get squeezed.so wavelength decreases and frequency increases.
Answer:
Magnetic field in Tesla: 1.65*10^−10 T, 0, 3.09*10^−10 T
Explanation:
Given data:
i = 4.8 A ,
dBx = 1.65*10^-10 T
dBy = 0 T
dBz = 3.09 * 10^-10 T
Attached below is the detailed solution
The weaknesses of the America government under the articals of confederation in which the Philadelphia mutiny highlighted include:
- Inability to regulate commerce.
- Inability to form a military.
<h3>What is a Mutiny?</h3>
This is a rebellious act among group of people in order to oppose a certain authority or government.
The government couldn't give soldiers a good working condition due to lack of funds which led to mutiny.
