Why is creativity important in constructing scientific methods? A. Science is a field that has nothing to do with creativity.
B. A scientific investigation always goes the way you expect it to.
C. There is only one experiment that can test each hypothesis.
D. The best way to test a hypothesis is not always the most obvious
way

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
