Which of the following statement is correct Car “X” has one quarter of the K.E of car “Y” Car “X” has half of the kinetic energy of car “Y” The two cars have the same KE Car “X” has twice the K.E of car “Y” 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 11 cms-1 1 cms-1 0.2cms-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 3 volts 5 volts 9 volts 10. The cyclotron frequency of an electron projected with velocity V perpendicular to a magnetic field B is given by f=2πeB/m f=eB/2πm f=mB/πc f=2πc/mB Loading … Pages: 1 2 3 4 5 6 7 8 9 10 11 12 13
