The work is an effect that is observed due to the application of force. Taking the concern of work-energy principle, the work is done when there is a transfer of energy take place.
When some magnitude of the force is being applied on an object to displace, then the term used to describe the effect is known as work done.
The mathematical expression for the work done is given as,
W = F × d
here,
F is the magnitude of applied force.
d is the displacement.
If we compare work with energy then, Energy, on the other hand, is the ability to do work. According to the work-energy principle, a change in the kinetic energy is equivalent to the net work done by the object. Therefore, energy is being transferred from one point to another when work is being done.
Thus, we can conclude that the work is done when a transfer of energy takes place.

The speed of sound varies in different mediums. In Physics, the speed of sound in air at 0°C is about 331.5 m/s, while in iron it's about 5130 m/s. If a train is 100 km away, the sound travelling through the iron rails would reach you approximately 282 seconds sooner than the sound through the air.
In Physics, the speed at which sound travels depends on the medium through which it's travelling. The speed of sound in air at 0°C is approximately 331.5 m/s. On the other hand, the speed of sound in iron is about 5130 m/s.
To determine how much sooner you would hear the train, we need to calculate the difference in time it takes for the sound to travel through these two mediums.
When the train is 100 km away, we get the following:
The difference is, therefore, approximately: 301.66 - 19.49 = 282.17 seconds. Thus, the sound will reach you 282 seconds sooner if you listen to the rails rather than the air.
