Step-by-step explanation:
Just perform the operations eg 46 - 9 = 37.
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.

Answer:
Value of x = 2,500
Step-by-step explanation:
Given:
700, 1200, 1600, 2000, x
Mean = 1,600
Find:
Value of x
Computation:
Mean = Sum of all number / Total number
1,600 = [700 + 1200 + 1600 + 2000 + x] / 5
Value of x = 2,500
