Ответ:
The correct option is c. about 1/10 as great
Explanation:
The problem can be understood by the concept of impulse. Impulse is a integral of force.
Impulse = Force × Time
As when we bend our knees upon reaching the ground the time of contact is about 10 times that of a stiff-legged. so,
= 10 × Time
So the force will be:
Force =
Force =
Force = ×
Hence the force is one tenth of the total as seen by the calculation.

The orbital diagram represents the filling of electrons in the sub levels of an orbit. The filling of the orbitals in sub- levels follow some basic rules and principles.
The orbital diagram of an orbit containing 16 electrons will be as follows:
1s²2s²2p⁶3s²3p⁴
The maximum number of electrons in each sublevel of the orbitals are: 2 electrons for s-sublevel with one orbital 6 electrons for p-sublevel with three orbital 10 electrons for d-sublevel with five orbital 14 electrons for f-sublevel with seven orbital
