5V R -Vin Problem A: If C1 is reduced, will that improve frequency response of the first stage? C1 Vsig' O HI. Problem B: In a certain application R = 10k. If all resistors are changed to 20k, will the frequency response of the first stage be affected, and if so, how. R Problem C: Vsig is a 1Vpp sine wave whose frequency is in the passband of both stages. If the first stage is omitted, and Vsig is fed directly to op amp input Vin, will the signal be amplified linearly? C2 5V R R Vout

Two current-carrying loops are shown in the figure below. What is the direction of the force on the left loop? XI C. A. D. E. F. out of the page into the page B.

50 cm-> 10 cm 8.0 A R = 1.0 x 10-3 A small circular loop of wire of radius 5 cm and resistance 1E-3 Q is centered inside a large circular loop of wire of radius 50 cm. The larger loop, which initially carries a current of 8 A, is cut and its current is reduced to zero over a time interval of 1E-6 s. Our goal will be to find the average current in the smaller loop during this time interval. (The magnetic field of the larger loop is approximately constant over the smaller loop.)

I am struggling to solve the problem. Would love some assisstance on it as I'd like to complete the problem within the hour.
