Moving with a speed of v km/hour, a train travels the distance between the points A and B, which is 600 km, in t hours. Find the
1 answer:
<h2>Formula which describes v in terms of t is 
</h2>
Explanation:
A train travels the distance between the points A and B, which is 600 km
Distance between A and B = 600 km
Speed of train = v
Time taken by train = t
We know that
Distance traveled = Speed of travel x Time taken
600 = v x t
Formula which describes v in terms of t is

We define our values according to the text,
R= Radius
Velocity
Strenght of the vortex filament
From this and in a vectorial way we express an elemental lenght of this filmaent as . So,
Where imply a vector acting perpendicular to both vectors.
Applying Biot-Savart law, we have,
Substituting the preoviusly equation obtained,
So we can express the velocity induced is,
