A magnetic field passes through a stationary wire loop, and its magnitude changes in time according to the graph in the drawing. The direction of the field remains constant, however. There are three equal time intervals indicated in the graph: 0 - 3.0 s, 3.0 - 6.0 s, and 6.0 - 9.0 s. The loop consists of 43 turns of wire and has an area of 0.13 m2. The magnetic field is oriented...

1. Heat opens capillaries and improves blood flow. The reverse is true too: cold capillaries close. Thus, for a black eye where you want to prevent blood buildup causing painful swelling, you use ice. Now consider a patient who is told to keep hot compresses on an eye infection for 10 minutes. She discovers that her compress is no longer hot after only 5 minutes and therefore wants to keep it warm twice as long. Is the better strategy to use...

A long straight wire has a hollow spherical conductor of radius R hanging from its end. The wire carries a downward current I. You are curious about the magnetic field, if any, that might exist just outside the "equator" of the sphere, i.e. the circle created by the intersection of the surface of the ball with a horizontal plane through its center, shown by the solid line a) What is the amount of charge on the sphere as a function...

New Jersey state lawmakers last year passed a bill that would
have required the Drinking Water Institute to formulate a state
regulation, known as a maximum contaminant level (MCL), for TCP.
Governor Chris Christie refused to sign the bill. The discovery of
the chemical 1,2,3- trichloropropane (TCP) in two public water
wells has recently renewed concerns from residents in the
Burlington County, NJ community.

Last year, you graduated from University with a diploma in Business Management and were able to get a full-time job immediately after graduation. After working for one year, you have $10,000 of savings! This happens to be the same amount that is outstanding on your student loan, so you are thinking about paying off your student loan fully. However, you are also considering a few other options for either spending or investing your savings. First, you think that it might...
