Answer:
Carbon has 6 electrons.
Before I answer, here's what you need to know.
There are 7 shells. Each shell can hold a certain amount of electrons.
1: 2
2: 8
3: 18
4: 32
5: 32
6: 18
7: 8
Carbon has 6 electrons, remember? So shell 1 is already completely filled. Shell 1 completely full, so onto shell 2.
Shell 2 needs 8 electrons, but carbon only has 4 to give, so 2, 4.
I hope this helps!
Answer:
The distance between the 1st order blue fringe and the 1st order red fringe is 6.5 cm.
Explanation:
Given that,
Diffraction grating =1300 lines/cm
Distance of screen = 2 m
Order number = 1
We need to calculate the distance between the 1st order blue fringe and the 1st order red fringe
Using formula of distance
For first order red fringe





For first order blue fringe


We need to calculate the distance between blue fringe and red fringe



Hence, The distance between the 1st order blue fringe and the 1st order red fringe is 6.5 cm.
Well, wind can change landforms by storms, and hurricains, or other things that contain air...

Like, over a period of time... Wind can make landforms decrease in size, by weathering.
