The voltage, v (in volts), across a circuit is given by ohm's law: v=ir, where i is the current (in amps) flowing through the circuit and r is the resistance (in ohms). if we place two circuits, with resistance r1 and r2, in parallel, then their combined resistance, r, is given by 1r=1r1+1r2. suppose the current is 3 amps and increasing at 0.02 amps/sec and r1 is 4 ohms and increasing at 0.4 ohms/sec, while r2 is 3 ohms and decreasing at 0.2 ohms/sec. calculate the rate at which the voltage is changing.

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
