An electron shell can hold 2(n^2) electrons (technically) where n is the shell number, i.e. shell 1 can hold 2, shell 2 can hold 8, 3 holds 18 and so on.
The atomic number of Nitrogen is 7, i.e. it has 7 electrons (to match its 7 protons, assuming it isn't an ion).
With the atomic number, you simply start from shell 1 and work out. So we put 2 electrons in shell 1, leaving us with 5 left. Shell 2 can hold 6 so we can fit all 5 in.
In other words, you should have 2 electron shells on the atom, shell 1 with 2 e- and shell 2 with 5 e-.
Answer:
t=L/
Explanation:
<u>solution:</u>
Let E be an observer, and B a second observer traveling with velocity 
as measured by E. If E measures the velocity of an object A as 
then B will measure A velocity as
= -
Applied here,
the walkway (W) and the man (M) are moving relative to Earth (E}, the velocity of the man relative to the moving walkway is
= 
-

The time required for the woman, traveling at constant speed relative to the ground, to travel distance L relative to the ground is
:

Explanation:
Impulse is the product of force and change in time or a measure of the change in momentum. Mathematically, Impulse is given as
J = FΔt
Where
J = Impulse,
F = Force,
Δt = change in time.
Due to the varying force, we know that the impulse varies at different points in the motion. Hence, the Net Impulse will be the addition of the individual impulses, i.e.
J = ΣJᵢ
J = J₁ + J₂ + J₃
J = F₁Δt₁ + F₂Δt₂ + F₃Δt₃
=> J = (24*2) + (24*4) + (0*2)
J = 48 + 96 + 0
J = 144 Ns
Answer:
When force and displacement are in the same direction, the work performed on an object is said to be positive work. Example: When a body moves on the horizontal surface, force and displacement act in the forward path. The work is done in this case known as Positive work.
