Tossup 20: Science (Physics) 
Carbon-13 is,though carbon-12 and carbon-14 are not. Photons and gluons are not, thoughleptons 
and quarks are.In general, an even number of these particles together is a boson, but an odd 
number together remains one of this type of particle. Because theirwavefunctions are 
antisymmetric, they obey Fermi-Dirac statistics rather than Bose-Einstein, and therefore obey the 
Pauli exclusion principle.Name this type of particle that has half-integer spin, named after an Italian 
physicist. 
Answer: Fermion 

Bonus 20: Math (Algebra) 
Find al the real zeros of the folowing polynomials.

C: 5 x squared + 14 x - 3 
D: x to the fifth power + 5x to the fourth power + 10 x cubed + 10 x squared + 5 x + 1 
Answers: (must have al answers in any order, but no additional answers) A: 6B: root 2, negative 
root 2,-7 C: -3 and 1/5 (1/5=.2) D: -1
