<h3><u>Answer;</u></h3>
Expulsion of electrons with varying frequencies of light observed in the photoelectron effect.
<h3><u>Explanation</u>;</h3>
- <em><u>The photoelectric effect supports a particle theory of light in that it behaves like an elastic collision between two particles, the photon of light and the electron of the metal.</u></em>
- Albert Einstein observed the photoelectric effect in which ultraviolet light forces a surface to release electrons when the light hits. He explained the reaction by defining light as a stream of photons, or energy packets.
Answer:
In That Case, It Gets Rid Of The Heat By Evaporating Water (sweat). During Bicycling, A Typical 72.0 Kgperson's Body Produces Energy At A Rate Of About 501 W Due To Metabolism ... If the air temperature is the same as the temperature of your skin (about 30 ∘C), your body cannot get rid of heat by transferring it to the air.
Explanation:
they are the lithosphere (land), hydrosphere (water), biosphere (living things), and atmosphere (air).
As the temperature of the lead and helium is the same. Thus the average kinetic energy is also the same for lead and helium.
Reason:
It is given that a 5.0-kg bar of lead is placed inside a 12-L chamber filled with helium gas. The temperature of the lead and helium is the same. It is required to compare the average kinetic energy of the lead atoms and helium atoms.
The average kinetic energy is calculated as,
.
Here K is the average kinetic energy, R is the gas constant, N is the Avogadro's number, and T is the temperature.
As the temperature is the same for both lead and helium. As a result, the average kinetic energy is also the same for lead and helium.
