Answer:
Fluid fricton goes to Static friction and sliding friction goes to rolling friction
Explanation:
Mass of an individual atoms or molecules
Metals are good conductors because the molecules that are inside the metal are tightly packed together. This is why the heat moves through the metal quickly.
Here, Your Options are absent, but the elements that would most likely become a positive ion will be:
hydrogen, sodium, potassium, lithium, cesium etc.
Hope this helps!
Solar energy is a form of renewable energy that is harnessed using the technology of the photovoltaic cells. These cells are composed of semiconductors. When the light from the sun hits the semiconductor, the energy from the light particles, or photons, cause the electrons in the semiconductor to be 'excited'. When the electron moves across the semiconductor platforms, the electron flows, thus creating electricity.
Therefore, as much as possible, you want to capture all of the sun's light. This can be achieved when the Sun is high up the sky. But if there is low sun angle, then the concentration of the sun's energy that strike the PV cells would be lesser.
