Consider three straight infinitely long (parallel to each other), equally spaced wires (with distance d), each carrying a current i in the same direction.
assume the three wires are coplanar. (eg. they are lying on the x, y plane where z = 0) , if the middle wire is rigidly displaced a very small distance x (x < < d) upward(in the z direction) while the other two wires are held fixed. analyze and describe the resulting motion of the middle wire. be specific in terms of magnetic field and gravity.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.

Two objects of different mass start from rest, are pulled by the same magnitude net force, and are moved through the same distance. the work done on object 1 is 900 j. after the force has pulled each object, object 1 moves twice as fast as object 2. how much work is done on object 2?

Question 1 (5 pts): what is the maximum distance for which you can you resolve the two individual headlights of an on-coming truck as two separate lights rather than one if the headlights are separated by 2.00 m and your eye has a diameter of 1.00 centimeter? assume a wavelength of 500 nm.
