work done by gravitational force = mass × g × height
= mgh
= 5 × 10 × 8 N

Hi!
The correct answer is: C. It is the data value that appears the most often in the set.
<h3>
Explanation</h3>
The mode of a set of values is the number which is the most frequently appearing, or most repeating value in the range. The numbers that show one time each are
A - 16 , C - 25 , D - 3
While 13 appears three times with the dishes labelled
B , E and F
So, the value that appears the most times is 13, and hence 13 is taken as the mode of this data set
<h3>Hope this helps!</h3>
Answer:
Ionization potential of C⁺⁵ is 489.6 eV.
Wavelength of the transition from n=3 to n=2 is 1.83 x 10⁻⁸ m.
Explanation:
The ionization potential of hydrogen like atoms is given by the relation :
.....(1)
Here <em>E</em> is ionization potential, <em>Z</em> is atomic number and <em>n</em> is the principal quantum number which represents the state of the atom.
In this problem, the ionization potential of Carbon atom is to determine.
So, substitute 6 for <em>Z</em> and 1 for <em>n</em> in the equation (1).
<em> E = </em>489.6 eV
The wavelength (λ) of the photon due to the transition of electrons in Hydrogen like atom is given by the relation :
......(2)
R is Rydberg constant, n₁ and n₂ are the transition states of the atom.
Substitute 6 for Z, 2 for n₁, 3 for n₂ and 1.09 x 10⁷ m⁻¹ for R in equation (2).
= 5.45 x 10⁷
λ = 1.83 x 10⁻⁸ m
