Answer:
The energy of each photon can be transformed into kinetic energy and as this energy does not change, the energy of both photoelectrons remains constant,
Explanation:
The photoelectric effect was explained by Einstein, who assumed that the lz is made up of particles called photons each of a given energy, therefore the photoelectric effect can be explained as a collision of particles.
From this explanation we see that the intensity is proportional to the number of existing particles, when we double the intensity we double the number of particles, but the energy of each particle does not change, therefore if we use the conservation of energy.
The energy of each photon can be transformed into kinetic energy and as this energy does not change, the energy of both photoelectrons remains constant, only the number of electrons expelled changes.
<h2>Answer: free electrons</h2>
<u>Plasma</u> is known as the 4th state of matter and is itself ionized gas. In this sense, ionization consists of the production of ions, which are <u>electrically charged atoms or molecules due to</u><u> the excess or lack of electrons</u><u> with respect to a neutral atom or molecule.
</u>
That is why in this process there are always<u> free electrons</u>. Therefore in heating gas to create plasma can yield free electrons, and the correct option is D.
Answer:
The views of scientific knowledge can change over time. Changes can result from new science observations, but can also be affected by social, political or religious reasons.To develop a deeper understanding, we need to investigate the reason for that, that how it's happening why it's happening etc.
In a ceiling fan, electrical energy, N, is transferred to another form, M. Energy transfers are never 100% efficient. Some of the energy is "wasted" as heat. To what form is the electrical energy (N) transferred (M) to allow the ceiling fan to function? The answer B. Kinetic Energy
Explanation:Electrical energy (N) is transferred to: kinetic energy (M)
Electrical energy causes the fan blades to turn. The energy of motion is kinetic energy.
Answer:
A. Prism
Explanation:
In the experiment we are able to isolate different wavelengths by shining the light through a prism, which separates the different wavelengths through refraction.
