    Answer of 60 is C .. Impossible .Infact Sound needs medium to travel , so it cant travel in vaccum .


      answer of 60 will be option A….. as sound is a mechanical longitudinal wave…. so sound will travel faster in a medium which is more elastic… in this question steel is more elastic than the rest mediums…

    48 wrong

    • Vis

      it is correct


    Respected sir,

    we did a research on electric motor.but, we
    wants to know the law that on which particular law it works.i hope that you
    help me because it’s new invention by us and you would like our experiment.

    5HP motor

    2.Aluminium Plate

    3 Neodymium magnet fixed in cast iron plate (
    28 pieces of magnet at equal interval around circular plate)

    we attached aluminium plate with 5 hp
    motor and start the motor .so, plate rotates with motor. now, we bring the.Neodymium
    magnet fixed in cast iron plate near by
    aluminium plate so due to MAGNETIC Flux DISTARB

    so we want to know the
    exact working law behind this process. I hope you will reply me as soon as
