1.) We consider a thin metal strip with conductivity o and thickness d oriented in the (x,y)-plane and moving at constant velocity v = vj in the y-direction, as shown. The metal strip falls in the air gap between the rectangular pieces of an electromagnet. The cross-sectional with of each pole is w along the r-direction) and length 1 (along the vertical). The electromagnet produces the magnetic field B = Bk (out-of-the-page). We treat this problem approximately by considering the...

Speaking of research designs, what are the key distinguishing features of the different research designs we discussed in class (e.g., experimental, quasi-experimental, correlational, archival, survey research)? Can you identify the IV, DV, and research design for a given scenario, similar to the first exercise we completed in class? Which design is most popular in I/O psychology?
