I am struggling with physics 5C due to having a horrible physics professor who is hard to understand and read his handwriting. Although I've tried studying via Khan Academy, I am still struggling immensely with homework problems. I'm hoping someone can help walk me through step by step how to solve problems 5.1, 5.2, 5.3, and 5.4. This would be immensely appreciated, thank you !

Physics 5C - Problem Set 5 Due Monday, May 6 at 11:59 PM on Gradescope UCLA / Spring 2024 / Brian Naranjo Problem 5.1 Ro Ro Ro Ro Ro Ro MV Ro Ro Ro Ro Ro . . . M M Ro Ro Ro Ro Ro Ro Assume the infinite resistor ladder shown above has a finite resistance R across its terminals. This is reasonable, as we see that the effective resistance should be greater than 2Ro and less than 3Ro. If we then add another "rung" to the resistor ladder, shown below, the resistance across the terminals should still be equal to R. Ro Ro R M Ro Use this information to set up a quadratic equation in R and then show that R = Ro(1 + V3) Problem 5.2 12 Eo 13 03 Ro Ro Ro In the circuit above, find the magnitude and direction of the the three indicated currents. The direction of the current is indicated by the sign of your result. For example, if you find /1 > 0, then the current is indeed flowing clockwise. You will use the junction rule and the loop rule. Furthermore, an appeal to symmetry will make your work easier. 5-15-2 Problem 5.3 I I 80 I:; 81 Ry Ry 2Ry In the circuit above, the central current is L= 250+ & 3= 5R0 . Find the magnitude and direction of the two remaining currents. Problem 5.4 S 'r RO & | ICD ]Cg In the circuit above, switch S is initially open and the capacitors are uncharged. At time = 0, the switch is closed. As functions of time , find the power Pg(t) delivered by the battery, the total power Pp(t) dissipated in the resistors, and the total energy U(t) stored in the capacitors
