Explanation:
From the question we are told that
The energy required to ionize boron is
Generally the ionization energy of boron pre atom is mathematically represented as
Here is the Avogadro's constant with value
So
=>
Generally the energy required to liberate one electron from an atom is equivalent to the ionization energy per atom and this mathematically represented as
=>
Here h is the Planks constant with value
So
=>
Answer:-
As we can see from the graphical data,
The distance covered by all the four runners is the same 5 km.
Among the four athletes, Athlete P covers the distance in under three hours.
It is the minimum time taken among the four athletes.
Thus Athlete P covers the 5 km distance in the minimum amount of time.
We know that speed =
Since time taken for P is minimum, his speed is the maximum. P ran the fastest.
Time taken by Q = 4.5 hours.
Speed of Q =
=
= 1.1 km/ hr
Time taken by R = 6 hours.
Speed of R =
=
= 0.8 km/ hr
