9)
a) for all rational number the number is positive and reciprocal is
negative
b) there is some rational number if the number is positive then the
reciprocal is negative
c) for all rational numbers if the number is positive then the
reciprocal is negative
d) there is some rational number that is positive whose reciprocal
is negative
so the answer is option D
10)
a) among the group of friends everyone knows everyone
b) among the group of friends everyone knows somebody in the
group
c) among the group of friends some people knows everyone
d) N is not related to the question so this is not the answer
so the answer is option A

1. Show that the Lagrangians L(t,q, y) and Īct, 4, ) = L(1,4,0) + f/10, 9) yield the same Euler-Lagrange equations. Here q e R and f(t,q) is an arbitrary function. 2 Lagrangian mechanics In mechanics, the space where the motion of a system lies is called the configuration space, which is usually an n-dimensional manifold Q. Motion of a system is defined as a curve q : R + Qon Q. Conventionally, we use a rather than 1 to...
