Explanation:
The voltage change across a resistor is negative when you traverse in the opposite direction of the current.
Answer with Explanation:
Given that
Thus by definition x component of velocity in Lagrangian system is given by
Thus by definition y component of velocity in Lagrangian system is given by
Since in eulerian system we need to eliminate time from the equations
From euations 'i' and 'ii' we can write
Applying these values in the velocity components as obtained in Lagrangian system we get
