1.	In a streamline flow,(a) the speed of a particle always remains same(b) the velocity of a particle always remains same(c) the kinetic energies of all the particles arriving at a given point are the same(d) the momenta of all the particles arriving at a given point are the same.
Answer» (c) the kinetic energies of all the particles arriving at a given point are the same (d) the momenta of all the particles arriving at a given point are the same. EXPLANATION: The speed and the velocity of a particle in a streamline flow may change as it moves ahead so (a) and (b) are not true. All the particles arriving at a point in a streamline flow have the same velocity. Hence all the particles arriving at that point will have the same kinetic energy and the same momentum. Options (c) and (d) are true.

Answer»

(c) the kinetic energies of all the particles arriving at a given point are the same
(d) the momenta of all the particles arriving at a given point are the same.

EXPLANATION:

The speed and the velocity of a particle in a streamline flow may change as it moves ahead so (a) and (b) are not true.

All the particles arriving at a point in a streamline flow have the same velocity. Hence all the particles arriving at that point will have the same kinetic energy and the same momentum. Options (c) and (d) are true.
