C. For wire m to be levitated. what is the direction of its eurrent ? d) Find the mas m of the third wire. Your answer should be in terms of , I, Im, a, h, g, and l

The beam from a laser is focused with a lens, reducing the area of the beam by a factor of 2. By what factor does the amplitude of the electric field increase?A. The amplitude does not change.B. The amplitude increases by a factor of √2.C. The amplitude increases by a factor of 2.D. The amplitude increases by a factor of 2√2.E. The amplitude increases by a factor of 4.

I Review | Constants Part A At the equator, the earth's field is essentially horizontal; near the north pole, it is nearly vertical. In between, the angle varies. As you move farther north, the dip angle, the angle of the earth's field below horizontal, steadily increases. Green turtles seem to In what direction should current pass through the coil, to produce a net field in the center of the tank that has a dip angle of 62° ? use this dip angle to determine their latitude. Suppose you are a researcher wanting to test this idea. You have gathered green turtle hatchlings from a beach where the magnetic field strength is 50 µT and the dip angle is 56°. You then put the turtles in a 1.2-m-diameter circular tank and monitor the direction O clockwise O counterclockwise Submit Request Answer in which they swim as you vary the magnetic field in the tank. You change the field by passing a current through a 100-turn horizontal coil wrapped around the tank. This creates a field that adds to that…

The NOAA Space Weather Scales describe three types of space weather storms: Geomagnetic storms, Solar Radiation storms, and Radio Blackouts.  A single large solar event can result in all three types of storms being observed at Earth.  Assuming a single solar event causes all three to occur, in what order would we expect to observe the three storms? Choose the correct order from the options below.  The storms are listed by arrival time, from first to last. A. First Geomagnetic, then Solar Radiation, then Radio Blackout. B. First Solar Radiation, then Radio Blackout, then Geomagnetic. C. First Radio Blackout, then Geomagnetic, then Solar Radiation. D. First Geomagnetic, then Radio Blackout, then Solar Radiation. E. First Radio Blackout, then Solar Radiation, then Geomagnetic. F. First Solar Radiation, then Geomagnetic, then Radio Blackout.
