Argand Complex Diagram Drawing Voltage

AI Thread Summary

To draw an Argand diagram of complex voltage at t=π/1800, start by calculating the instantaneous voltage using the equation i = lcos(ωt). The resulting voltage can be represented as a point in the complex plane, where the horizontal axis represents the real part (voltage) and the vertical axis represents the imaginary part (current). To accurately depict the voltage, plot the calculated values at the specified time and ensure the projection on the horizontal axis reflects the voltage magnitude. Understanding the relationship between the real and imaginary components is crucial for a correct representation.

but what's d method of drawing it

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
