Consistent system

Consider a system consisting of two identical balls each of mass M connected by a light rigid rod as shown in figure. An impulse J=MV is imparted to the system at one of its ends. The angular velocity of the system would be

Every system of dependent equations is consistent. Is the converse always true ?

A receiver of communication system consists of

A basic communication system consist of ( a ) transmitter ( b ) information source ( c ) channel ( d ) receiver Choose the correct sequence in which these are arranged in a basic communication system:

Let AX=B be a system of n-linear equations in n-unknowns ( in the usual notation ) such that A is a non singular matrix , then the system is consistent and has a unique solution given by

A telephoton system consists of two glass balls with radii R_(1) = 5.0 cm and R_(2) = 1.0 cm . What are the distance between the centres of the balls and the magnification of the system if the bigger ball serves as no objective ?
