Answer:When electrons in atom interaction with light or photons one of the two process takes place:

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.

WARRIOR [948]

Answer:

The correct answer is 5.

Step-by-step explanation:

This is because if you divide 10 by 2 and -15 by 3

you get 5. Now to double check, you can do 10/5 and -15/5

This will give you 2, -3, which is the coordinates.


Hope this helps!

Using factoring, which values are the solutions to the quadratic equation 2m2+7m−30=0?
Luden [163]

Answer:

B: m = -6 or m = 5/2

Explanation:

\rightarrow \sf 2m^2 +7m - 30 = 0

<u>breakdown</u>

\rightarrow \sf 2m^2 +12m -5m- 30 = 0

<u>take out common factor</u>

\rightarrow \sf 2m(m +6) -5(m+ 6) = 0

<u>collect into groups</u>

\rightarrow \sf (2m -5)(m+ 6) = 0

<u>set to zero</u>

\rightarrow \sf 2m -5=0, \ m+ 6 = 0

<u>change sides</u>

\rightarrow \sf m=2.5, \ m= -6

Answer:

  • D. 32 times; 5/4*40 = 32

Step-by-step explanation:

It is expected the spinner to land on Red 1/5 times.

<u>If the spinner is spun 40 times, then it should land on Red:</u>

  • 1/5*40 = 8 times

<u>And it should not land on red:</u>

  • (1 - 1/5)*40 = 4/5*40 = 32 times

Correct choice is D
