Using polar coordinates, integrate the function \(2x+2y\) over the unit disk.

A conducting bar with dimensions L = 13 cm, h = 3.9 cm, d = 1.5mm is connected in series to a power supply with emf= +115V. The bar is oriented along the x axis. A voltmeter is attached vertically across the bar, with leads directly across from each other, as shown, and reads +1.8 x 10–5 V. There is a uniform magnetic field of 0.7 T in the –z direction throughout this space due to large coils that are not shown in the diagram. What is the sign of the charge carriers and the drift speed of these charges in the bar?

Using polar coordinates, integrate the function \(2x+2y\) over the unit disk.

The figure below shows the path of an electron traveling in the xy plane. The gray boxes show two regions containing uniform magnetic fields, B1 and B2 , both perpendicular to the screen. There are no other fields or interactions other than the magnetic fields shown in the diagram. Which of the following statements are correct? I. The magnetic field B1 points out of the page and B2 points into the page. II. The electron is traveling faster in the region B2 than through B1. III. The magnitude of B1 is larger than that of B2.
