1. A negative charge, -q, has a mass, m, and an initial
velocity, v, but is infinitely far away from a fixed large positive
charge of +Q and radius R such that if the negative charge
continued at constant velocity it would miss the center of the
fixed charge by perpendicular amount b. But because of the Coulomb
attraction between the two charges the incoming negative charge is
deviated from its straight line course and attracted to the fixed
charge...

Σ={a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z}.
In how many of these permutations do
a,b,c occur consecutively and in that
order?
In how many of these permutations does a appear before
b and b appear before c?

(complexity theory): let language C be:
C = {<p,n> | p and n are natural numbers and there is no
prime number in the range [p,p+n]}
a)explain if the given explanation is good, or if it is bad,
explain why: a professor wanted to prove that language C belongs to
class NP like this: "for each word <p,n> that belongs to C,
there is a confirmation that proves its belonging to the language:
the confirmation is formulated by a non...
