Here the block has two work done on it
1. Work done by gravity
2. Work done by friction force
So here it start from height "h" and then again raise to height hA after compressing the spring
So work done by the gravity is given as

Now work done by the friction force is to be calculated by finding total path length because friction force is a non conservative force and its work depends on total path


Total work done on it

So answer will be
None of these
At a distance of 1.33 m 250-N load be hung on the pole, such that the father will carry twice the load of his son.
<h3>What is torque?</h3>
Torque is the force's twisting action about the axis of rotation. Torque is the term used to describe the instant of force. It is the rotational equivalent of force.
Torque about the left end ;

From the observation,

After rearranging equation, we get;

Substitute the value of the obtained force we get;
x=1.33 m
Hence, at a distance of 1.33 m ,250-N load be hung on the pole, such that the father will carry twice the load of his son.

The medical understanding of death is related to the scientific approach, and the popular understanding is related to the inclusive spiritual and cultural approaches.
<h3 /><h3>What is death for science?</h3>
Death occurs when an individual's cardiorespiratory and brain functions cease due to some factor, thus ending his life.
Popular understanding, on the other hand, is aligned with scientific knowledge, but it is also encompassing cultural and religious teachings, which define topics not proven by science, such as life after death for example.
Therefore, death is a delicate topic for society, and spirituality is the basis found for greater emotional comfort in individuals who suffer significant losses of loved ones.
