How do exited atoms give off light

Light is produced by the change of state of energy of an electron. Within an atom, there are multiple electron "shells". 'Excited' atoms are those where the electrons are moving in between shells. The electrons move because they are given energy enough to move to a different shell; however, they are unstable and cannot remain in their new position. When moving back to its original shell, the electron loses energy - but energy can't be created nor destroyed so they release a photon. 
There's other ways light may be produced, but always it is produced as a result of transmission of energy (in some form). Also, light is usually produced in conjunction with other forms of energy such as sound or heat.

From my research, the image supports the question. From the graph given, we can construct the equation of the line using the two-point formula. Using the given value of 601 K, we can solve for the missing value of altitude.

y - y1 = [(y2 - y1)/(x2 - x1)](x- x1)
y - 147.52 = [ (567 - 147.54)/(78.11 - 18.4) ](x - 18.4)

Substituting y = 601 to solve for x:
601 - 147.52 = [ (567 - 147.54)/(78.11 - 18.4) ](x - 18.4<span>)
</span>x = 83

Therefore, the probe's instruments will fail at 83 kilometers.

The Sun's declination is 0° at the _________. A. summer and winter solstice B. summer and winter equinox C. vernal and autumnal
Olegator [25]

-- "Declination zero" means the object is in the sky at some point directly over the Earth's equator.  

-- If it's the sun and it appears to be over the equator, then that tells us that the Earth's axis is not tilted toward or away from it.  

-- That in turn tells us that the Earth is at one of the two equinoxes in its orbit, either the Spring one or the Autumn one. <em> (D)</em>

-- (The first days of Summer and Winter coincide with solstices, not equinoxes.)

An object is moving in a straight line at constant speed. A resultant torce begins to act upon
alekssr [168]

Answer: The velocity magnitude or the velocity direction chages.

Explanation:

According to Newton's second law of motion, the acceleration of a system moved in same direction and is also directly proportional to the external force which acts on it while inversely proportional to the mass. The formula is: a = F/m

Based on the question, since the object obtains acceleration, then it can be infered that there will be changes in the velocity magnitude or the direction as a result of the motion.

An amplifier has a 50 watt output and a 5 watt input. what is the gain in decibels for this amplifier, rounded to the nearest de
Marrrta [24]
Gain in decibels is given by;

Gain db = 10*log (Po/Pi), where Po = Power output, Pin = Power input

Substituting;

Gain in db = 10 * log (50/5) = 10 db

.Which of the following scenarios correctly describes Newton's First Law?
hodyreva [135]

Answer:

A chair that for some reason won't move even after being pushed.

Explanation:

Newton's first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. This postulate is known as the law of inertia.

Hope this helps! Sorry if I'm wrong.
