2. Imagine two identical simple circuits, each with a switch and the same battery and light bulb (resis- tance R). Each circuit is wrapped round a cube-shaped box of side d = 1 m and mass m =1 kgm. One box is nailed to the floor it doesn't move. The other box is free to slide over a smooth surface. Each bulb is rated with a power of P observed that the mobile box, initially at rest and starting 10 cm distant, moves away from the fixed box when the switches are flipped and the bulb lights. At a distance of 1 m away from the fixed box, the mobile box is moving with a speed of 1 ms. Suppose that all segments of the wire save the two sides facing each other are shielded - they neither emit nor admit magnetic fields. 100 watts, and in this circuit, yields with this power. It is a) What must be the potential of the battery? b) What must be the resistance of the bulb? c) What must be the orientation of the currents?
for this the solution just said non-inverting v0=vs((10k/10k )+1) v0=2vs first of all what is non-inverting and how do i know if it is inverting or non-inverting and what is the difference between both in application? and how did he just get the other equation? i dont get it. please explain everything in a lot of detail and provide an altered question for one that is inverted and solve it so i can understand the difference in application. thank you!

Switch S1 has been closed and S2 has open for a long time until the capacitors are fully charged. At t=0, S1 is opened and S2 is closed. If x=12V, C₁-4mF and C₂-8mF, R₁ =3.91k0 and R₂-2.76 kQ; what is the current passing through R₂ at t=0 in units of mA? Please express your answer using two decimal places. E R₁ www 50 11 a b S R₂

Although we are given the restrictions on Kd and Kp, explain how we arrived at that conclusion and show all work necessary to arrive at the given solution for each restriction.
It is common, in the analysis of electrical circuits, to determine voltage drops over resistors specific. If these are passed in circuits formed by independent sources, the principle of superposition is the technique used to solve this problem. He process that, for that, the current sources must be open-circuited and the voltage sources must be shorted. when doing this in the circuit presented below, determine a voltage drop across resistor R1.
