A person is bungee jumping. The bungee cord is attached to a bridge over a river. At time t0, before the person jumps (and while she is at rest), the bungee cord is unstretched. At time t1, the cord is stretched and the person is moving downward at her maximum speed. At time t2, the person has fallen her maximum distance and the cord is stretched by its maximum amount. At t3, the person is moving back up toward the...

Conducting Loop and Current-Carrying Wire

An infinite straight wire carries current I1 = 5.8 A in the positive y-direction as shown. At time t = 0, a conducting wire, aligned with the y-direction is located a distance d = 51 cm from the y-axis and moves with velocity v = 19 cm/s in the negative x-direction as shown. The wire has length W = 24 cm.1) What is ε(0), the emf induced in the moving wire at t = 0? Define the emf to be...

When should a person execute a durable power of attorney? What preferences does an advance directive establish? When is CPR indicated, and when is it not? How would you explain the statement that “CPR should not be the standard of care for the chronically ill resident of a long-term care facility”? Explain the difference between starvation and the malnutrition/dehydration of the dying process.

In Figure 20.15, a rectangular current loop is carrying current I1 = 7.0 A, in the direction indicated 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. If the net force on the loop is to have magnitude 1.7x10^-6 and is to be directed towards the wire, what must be the...

Parasitic power theft: A power line running East-West at 150kVAC carrying a 75 MWatt load is 10 meters overhead. A thief makes a 100 turn loop of insulated copper wire around a plastic garbage can with a 70cm diameter. The voltage generated in this coil is used to charge batteries for a fish-finder, lights and radio in his fish hut. The battery charger is electrically equivalent to a 5 ohm resistor. a) What orientation of the garbage pail winding will...

Radioactive waste can remain dangerous for a hundred thousand years. GE Hitachi created a new power plant that can use radioactive waste and reduce the storage requirements to 300 years. In GEH’s view, what is generally considered to be “nuclear waste” these days is not really waste at all. Light Water Reactor (LWR) used nuclear fuel is composed of 95 percent uranium, 1 percent transuranics, and 4 percent fission products. Many of these transuranic isotopes have long half-lives, which can...
