A flat rectangular loop of wire is placed between the poles of a magnet. It has dimensions w = 0.60 m and L = 1.0 m, and carries a current I = 2.0 A. The magnetic field due to the magnet is uniform and of magnitude 0.80 T. The loop rotates in the magnetic field and at one point the plane of the loop makes a 30° angle with the field. At that instant, what is the magnitude of the torque acting on the wire due to the magnetic field?

Consider an economy that produces only two goods: mandolins and fiddles. In 2010, 50 mandolins and 25 fiddles were produced. In 2011, 100 mandolins and 50 fiddles were produced. In 2012, 150 mandolins and 75 fiddles were produced. The price of a mandolin was $300 in 2010, $400 in 2011, and $600 in 2012. The price of a fiddle was $200 in 2010, $250 in 2011, and $300 in 2012.  Real GDP for 2012 (using 2011 as the base year) is

Suppose the price of a steak dinner was $20 in 2003. If the CPI was 200 in 2003 and 10 in 1903, what would the same steak dinner have cost in 1903?
