Work is defined to be force multiplied by distance. If one component of the equation is decreased while aiming to keep the resulting value, then the other component must be increased. In that sense, to keep the same amount of work while reducing the force, the distance where the force is exerted should be increased.
The correct answer is The harmonic law would suggest that Neptune will take a longer amount of time to orbit the sun then Mercury!

Answer:
Explanation:
The head decelerates from 4 m /s to zero in .2 sec so deceleration = 4 - 0 / .2
= 20 m/s²
If F be the average force acting on head
F - mg = ma
F = m ( g + a )
= 65 ( 9.8 + 20 )
= 1937 N .
This force will be uniformly acting on head in upward direction . So during first half and second half , deceleration is same hence force F will also be same .
