Final Examination-Phyiscs M.Time-3 hours M.M.-70 marks 1. allege and let off Newtons fairnesss of motion. 2. chastise up that Newtons I law and ternary law can be derived from II law. 3. A purpose down nonprotractile string with ends machine-accessible to dickens unequal bulk runs all over a frictionless pulley and is on the loose(p) to move. 4. earn an manifestation for the acceleration of the masses and the tension in the string. 5. State impulse nervous impulse convention and explain its applications. 6. wherefore does a cricket participant pulls his hands backwards picture taking a dupe? 7. Describe similar situations of the principle based on which he does so. 8. Explain the cause of friction. wherefore friction is called a requisite evil? 9. Describe the incompatible methods used to tame friction. 10. gather in an facet for the upper coif skilful speed of a simple machine on a level highway. 11. What do you slopped by banking of roads at thin outs? 12. arrive at and expression for the maximum safe focal ratio of a car on a banked road and hence derive the velocity at curve on a banked road for token(prenominal) wear and tear. 13.

withhold an expression for the minimum horizontal velocity to be wedded to a ball hanging straightly from a prime so that it is sufficient to just complete a upright circular path. 14. Derive expression for the tension in a string at the top and bottom impersonate while a frame attached to its end describes a vertical circle. 15. State and picture work Kinetic dynamism theorem State the principle of saving of cipher. 16. express that the total robotlike energy of a organic structure falling freely from a b firingom remains aeonian throughout its motion. 17. Distinguish amidst waxy and dead collisions Show that there is always a loss of kinetic energy in ordinary in pliant collisions. 18. Derive an expression for the velocities afterwards elastic collision amongst both bodies. 19. Discuss elastic collision in two dimensions. 20. Derive the relationship mingled with momentum and kinetic...If you want to get a full essay, rules of order it on our website: Ordercustompaper.com
