Car “X” is travelling at half the speed of car ‘Y” and mass of car “c” is twice as compared to the pass of car “Y”. Which of the following statement is correct Car “X” has half of the kinetic energy of car “Y” Car “X” has twice the K.E of car “Y” Car “X” has one quarter of the K.E of car “Y” The two cars have the same KE 8. If the wavelength of a transverse is 2cm and the period is 2 seconds then the wave speed in CGS is 0.1cms-1 0.2cms-1 11 cms-1 1 cms-1 9. A car battery has EMF of 12 volts and internal resistance 5x 10 ohm. If it draws 60 ampere current, then terminal voltage of the battery will be 15 volts 5 volts 9 volts 3 volts 10. The cyclotron frequency of an electron projected with velocity V perpendicular to a magnetic field B is given by f=mB/πc f=eB/2πm f=2πc/mB f=2πeB/m Loading … Pages: 1 2 3 4 5 6 7 8 9 10 11 12 13
