In a fission experiment observed by hahn and strassman, uranium-235 was bombarded by neutrons. the products of this ission reaction included two light nuclei, barium-137
and krypton-84. what was another product of this nuclear reaction?
water
energy
hydrogen-1
helium-4

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.)
