Every element is able to be recognized individually in many different ways. A very easy and common way is using light absorption also known as spectroscopy. Every atom has electrons, and these electrons like to stay in their lowest-energy configuration. However, when photons collide with an electron it can increase it to a higher energy level.. This is absorption, and each element’s electrons absorb light at specific wavelengths related to the difference between energy levels in that atom. But the electrons want to return to their original levels, so they don’t hold onto the energy for long. When they emit the energy, they release photons with exactly the same wavelengths of light that were absorbed in the first place. An electron can release this light in any direction, so most of the light is emitted in directions away from our line of sight. Therefore, a dark line appears in the spectrum at that particular wavelength.

Because the wavelengths at which absorption lines occur are unique for each element, astronomers can measure the position of the lines to determine which elements are present in a target. The amount of light that is absorbed can also provide information about how much of each element is present.

If you fell 90ft while sitting down strapped in an elevator (think tower of terror ride) would you die when the elevator hit the

8_murik_8 [283]

Probably not. The elevator has security system just like any device. It will automatically trigger breaks in case it detects some sort of free fall.

Person inside free falling elevator could experience 0G or no gravity effect something similar to what astronauts experience in earth's orbit.

The only damage that could happen to you is when the breaks are released you won't feel 0G anymore and fall about 4ft to the floor of the elevator.

Hope this helps.

what is the average acceleration of a four wheeler that speeds up from 3 miles per hour to 15 miles per hour in 0.6 hours

den301095 [7]

A= change in velocity / change in time

$a = \frac{change \: in \: velocity}{change \: in \: time}$
$a = \frac{15 - 3}{0.6}$
$a = 20 \: \frac{m}{ {s}^{2} }$

Where is the light energy converted into an electron flow.

schepotkina [342]

During photosynthesis, light energy is converted into an electron flow in the reaction center chlorophyll.

<h3>What is photosynthesis?</h3>

Photosynthesis can be defined as a biological and chemical process through which green plants (autotrophs) convert light energy (sunlight) into chemical energy.

<h3>The chemical reaction for photosynthesis.</h3>

In Science, photosynthesis is represented by the following chemical reaction:

$Carbon \;dioxide + water + light energy \rightarrow sugar + oxygen$

In conclusion, the electrons found within the pigment molecules are excited by visible light, which is then converted into an electron flow in the reaction center chlorophyll.
