Sometimes neutrons are also produced. This decomposition is called fission, the breaking of a large nucleus into smaller pieces. The breaking is rather random with the formation of a large number of different products. Fission usually does not occur naturally, but is induced by bombardment with neutrons. The first reported nuclear fission occurred in 1939 when three German scientists, Lise Meitner, Otto Hahn, and Fritz Strassman, bombarded uranium-235 atoms with slow-moving neutrons that split the U-238 nuclei into smaller fragments that consisted of several neutrons and elements near the middle of the periodic table. Since then, fission has been observed in many other isotopes, including most actinide isotopes that have an odd number of neutrons. A typical nuclear fission reaction is shown in Figure 21.14. Q: The first reported nuclear fission occurred in 1939 when three german scientists bombarded uranium-235 atoms with slow-moving what? A:
A:
output: neutrons

Answer the following question given this paragraph: Earth's magnetic poles have switched places repeatedly in the past. As you can see in the Figure below , each time the switch occurred, Earth's magnetic field was reversed. The magnetic field is the region around a magnet over which it exerts magnetic force. We think of today's magnetic field direction as "normal," but that's only because it's what we're used to. You can watch a simulation of a magnetic field reversal at this URL: http://www. pbs. org/wgbh/nova/earth/when-our-magnetic-field-flips. html. Q: The earth's magnetic poles have done what repeatedly in the past? A:

OPTIONS:
- rotated
- stayed the same
- demagnetized
- switched places

Answer: switched places

Q: Answer the following question given this paragraph: Electrical energy is useful to us mostly because it is easy to transport and can be easily converted to or from other forms of energy. Of course, conversion involves wast, typically as heat. Q: What type of energy is useful to humans because it's ease of transport and conversion to other forms of energy? A:

OPTIONS:
- physical
- potential
- heat
- electrical

A:
electrical
