Answer:
v_average = 15 m / s
Explanation:
The average speed can be found in two ways,
* taking the distance traveled and divide it by the time spent
* taking the velocities in each time interval and then finding the weighted average by the time fraction
v_average = 1 / t_total ∑ vi ti
Let's apply this last equation
Total time is
t = t₁ + t₂
t = 10 + 10 = 20 min
v_average = 10/20 10 + 10/20 20
v_average = 10/2 + 20/2
v_average = 15 m / s
Answer : The magnitude of the orbital angular momentum for its most energetic electron is,
Explanation :
The formula used for orbital angular momentum is:
where,
L = orbital angular momentum
l = Azimuthal quantum number
As we are given the electronic configuration of Fe is,
Its most energetic electron will be for 3d electrons.
The value of azimuthal quantum number(l) of d orbital is, 2
That means, l = 2
Now put all the given values in the above formula, we get:
Therefore, the magnitude of the orbital angular momentum for its most energetic electron is,
