1) they can absorb photons of a characteristic wavelength (which depends on the energy difference between two interacting atomic levels) and get excited to a higher energy level

2) or they can jump to a lower energy level and emit photons of the corresponding wavelength.

The type of spectrum produced when electrons in an atom undergo transitions to various levels by absorbing or emitting photons is termed as atomic spectrum.

Use the equation to answer the questions. Round both answers to nearest whole number. Y = 47.25 − 2.25 X If Y equals 8 , what is

noname [10]

Answer:

If Y equals 8, X is equal to 17.

If Y drops to 4, X is equal to 19.

Step-by-step explanation:

We know that the equation is $Y = 47.25- 2.25X$ and we want to find X when Y = 8. To do this we solve the equation for X.

$47.25-2.25X=8\\47.25\cdot \:100-2.25X\cdot \:100=8\cdot \:100\\4725-225X=800\\4725-225X-4725=800-4725\\-225X=-3925\\\frac{-225X}{-225}=\frac{-3925}{-225}\\X=\frac{157}{9}=17.4444...$

17.4444 rounded to the nearest whole number is 17.

If Y drops to 4,

$4 = 47.25- 2.25X\\47.25-2.25X=4\\47.25\cdot \:100-2.25X\cdot \:100=4\cdot \:100\\4725-225X=400\\4725-225X-4725=400-4725\\-225X=-4325\\X=\frac{173}{9}=19.2222...$

19.2222 rounded to the nearest whole number is 19.

I need yo help B, on dis question

Anna71 [15]

For this case we can use the law of the sine to solve the problem.
We have then:
$5 / sine (68) = 5 / sine (x)
$
From here, we clear the value of x.
We have then:
$sine (x) = (5/5) * (sine (68))
$
Rewriting we have:
$sine (x) = (1) * (sine (68))

sine (x) = sine (68)

x = arcsine (sine (68))

x = 68$
Answer:
The angle R is given by:
x = 68 degrees
option B
