4. Linear momentum of one object becomes half the intial linear momentum. Then there will be ……………% decrease in its kinetic energy.
5. Give the uitlity of the physical quantity phase.
(B) Answer any three in eight to ten sentences. : (6)
1. Write he equation of displacement of S.H.O. with the helpp of differentiation, obtain the equation of velocity in terms of displacement. Write the values and positions of maxmum and minimum velocities.
2. Derive differential equation of forced oscillation with damping.
3. A wave originate at x=0 at t = 0 with initial Phase ‘O’. If the wave is sinusiodal derive the equation y = Asin (wt-kx) at time t for a particle lying at distance x =x from the origin.
4. Define position vector of centre of mass, and explain centre of mass of a rigid body ?
(C) Attempt any THREE of the following Problems : (9)
1. A spring of length having its force constant K is cut into two parts. These parts have their length in 4:1 proporotion and their force constants are K1 and K 2 respectively show that K 1 and K2 = 5k..
2. Prove that for a wave Propagating in a medium, the ratio of instantaneous velocity of a particle of the medium to the wave velocity is equal to the negative value of the slope of the waveform at that Point.
3. An atom is executing simple harmonic osceillations with an amplitude of 2.5 x10-7 meter one is simultaneously emitting electromagnetic waves. These waves are recorded by a stationary recorder as shown in figure. If the velocity of waves emitted is 3 x 108 m/sec. Find out the maximum and the minimum frequencies as recorded by the recorder. The frequency of the oscillation of the atom is 2 x 1013 Hz. and it is emitting wave of the same frequency. Assume that the equations obtained for the Doppler effect for sound are also valid for electromagnetic waves.
4. Its one end is placed in water at c and other end is placed in ice at 0o c. At what distance from its hot end a flame of temperature c should be placed so that per unit time, same amount of water evaporates at the hot end as the amount of ice melts at cold end ? Latent heat of evaporation of water = 540 cal/gm. Latent heat of melting of ice is 80 cal/gm. A carnot engine is operating between 1000k and 500k. In order to extract work of 210 Joules per cycle from this engine how much heat must be absorbed from the source in each cycle (J = 4.2 joules/cal)
