Aluminum Fly Rod
Electromagnetism - 10 points/5 stars?
Thanks in advance for any help. 
10 points nad 5 stars to the first answer.
1. An aluminum airplane is flying west, parallel to the ground, at 350 m/s. The earth's magnetic field produces a downward component of 8.30 x 10^-5 T at that point. For the purpose of this question, treat the wings as if it was a conducting rod.
a) What is the magnitude of the potential difference applied across the plane's wingspan of 22 m?
b) Which wing would be negatively charged, the one on the south side of the plane or the one on the north side of the plane?
a) Let's first solve for the electric field by using the formula E = B*v.
E = (8.30 x 10^-5 T) x 350 m/s = 2.91 x 10^-2 V/m
Now solve for the potential difference by using the formula ?V = -E*d.
?V = (-2.91 x 10^-2 V/m) x 22.0 m = -0.640 V
b) The North side if I am not mistaken.
Fly Fishing Equipment: Reels
Your fly fishing reel can be as important as your fly fishing rod. At one time, many people thought of the fly fishing reel as just storage for your line, but it has evolved into so much more. The reel can make a big difference in being able to drag in your fish or failing to do so.
Most fly fishing reels are made of aluminum. When using, the fisherman strips line off the reel with one hand while casting with the other. He (or she) then retrieves the slack line by winding it back up on the reel. The type of reel you use depends on the fish you are trying to catch. Some reels are better suited for larger fish as well as more demanding conditions while on the water.
Your fly fishing reel should have a solid handle that is easy to manipulate. Some reels come with double handles - one on each end of the spinner - that makes it much easier to grab hold of and wind up. Which one you choose is up to you!
The spool holds the fishing line. Attached to the spool on the outside is a small weight called a counter balance. This assures that the reel spins smooth and true without any interference from the rod or the angler. Many spools have exposed rims. This actually serves a very useful purpose when you are struggling with a fish. You can cup your hand on the outside of the room so you can play with the fish and save your tackle if you are using light flies.
The drag on a fly fishing reel creates pressure and prevents the line from free spooling or back lashing. You can have a click drag on your reel which are springs that put pressure against a gear stopping it from moving. These reels are noisy, though, so keep that in mind. Disc drags are either pads or gears that have calipers like brakes on a car. As the pressure on the gear increases, the pad clamps down stopping the drag.
The reel clamps to your fly rod with a "seat" that clamps down on the handle with "feet". All reels are made to the same standard so the seats that are on fly fishing rods with handle all fly fishing reels. So, basically, you can pick out your rod and then choose the reel you want and not have to worry if it will fit your rod.
Choosing your fly fishing reel depends a lot on what type of fishing you will be doing. If fishing for large game fish, you will want one that can handle the pressure of the weight of the fish. If you are just fishing for trout and bass, you will want a standard reel that will make bringing your fish in just a little bit easier.

We began our July fishing adventures on a DeHavilland Beaver float plane with pilot and 4 passengers plus our gear for a day fishing at Big River Lakes. Light layers and neoprene chest waders were all the gear that was needed.
We left Lake Hood in Anchorage about 9 a.m. heading across Cook Inlet to Lake Clark National Park west of Redoubt Bay and arrived at our destination around 10:30 a.m.
The flight was easy and enjoyable with sunny skies, taking in the scenery of the Aleutian Range as we flew closer. We arrived and transferred our gear to a flat bottom aluminum boat and the pilot/guide took us across the lake to fish on the west shore beside the stream. The planes are parked on muskeg, much too soggy for fishing so the pilots do double duty and run the boats as well.
Big River Lakes is a series of interconnected lakes that are a popular fly-out fishing spot. There were at least 3 other airplanes there the day we went out. A nearby lodge is well suited for bear viewing and we shared the lake with many other boats.
Soon after we arrived a 400 pound black bear come in to the stream feeding from the lake and he was there maybe 5 minutes when he suddenly took off when a 3-4 year old, 800-pound boar brown bear showed up. The brown bear fished for about 30-40 minutes while we stayed on shore well away from him. Though the bear was calm and showed no aggression to us, everyone stayed on the boats and gave him plenty of respect allowing him access to his fishing hole. He wandered off down the bank of the lake and 30-40 minutes later a sow with 3 cubs showed up. The sow was teaching the cubs how to fish, but the cubs were more interested in simply playing in the lake and checking out the fishermen. The sow paid no attention to the humans gathered and seemed to have no interest in our presence.
After they ate their fill, they proceeded down the bank on the south side of the lake, leaving the peaceful lakes once more to the fishermen. As she disappeared, the male brown bear began to swim across the lake from the north bank to the south, a distance of about 500 yards. As he got to the south shore and went into the woods, there was a loud ruckus and we assumed the sow had a confrontation with the male who was chased off, though he was nearly 300 pounds more than the sow. Shortly the male emerged from the south shore and swam back toward the north shore.
Unconcerned about the antics of the local bear population, we continue our quest for the Red Salmon we had come to fish. We stayed on the lakes about 5 hours and everyone caught their limit, catching and releasing fish until we were ready to head back to Anchorage. With no rain, mild temperatures, and no mosquitoes, we had a wonderful day fishing.
