Which of the following is a purpose of nutrient intake?

As shown in the figure, an insulated wire is bent into a circular loop of radius 6.0 cm and has two long straight sections. The loop is in the xy-plane, with the center at the origin. The straight sections are parallel to the z-axis. The wire carries a current of 8.0 A. What is the magnitude of the magnetic field at the origin?

When it comes to IOL calculations for cataract surgery, the following statements are true, except:

Four capacitors are connected across a 90-V voltage source as shown in the figure.  (a) What is the charge on the 4.0-μF capacitor?  (b) What is the charge on a 2.0-μF capacitor?  (c) What is the charge on the 3.0-μF capacitor?  (d) What is the potential difference across the 6.0-μF capacitor?

A charged capacitor is connected to an ideal inductor. At time t = 0, the charge on the capacitor is equal to 6.00 μC. At time t = 2.00 ms the charge on the capacitor is zero for the first time. What is the amplitude of the current at that same instant?

As shown in the figure, a rectangular current loop is carrying current I = 3.0 A, in the direction shown, and is located near a long wire carrying a current Iw. The long wire is parallel to the sides of the rectangle. The rectangle loop has length 0.80 m and its sides are 0.10 m and 0.70 m from the wire, as shown. We measure that the net force on the rectangular loop as 4.9 × 10-6 N directed towards the wire.    (a) What is the magnitude of the current Iw?   (b) In which direction does Iw flow: from top to bottom or from bottom to top in the sketch?
