ICSE Physics objective test: Quiz 3


A bullet of mass 'a' fired with velocity 'b' into block of mass 'c' and remains embedded into it. The final velocity of the system is:





Potential energy can not be expressed in:





Energy is defined as:





Weightlessness produced in a space ship is due to:





A body comes running and sits on a merry-go-round. What is conserved?





A hollow cylinder and a solid cylinder of same mass and radius are made to slide down down an inclined plane, which one reaches the bottom first?





Longitudinal waves can not propagate through





If the source moves away with such a velocity from listener, who is at rest then the frequency of the note is halved. Then its velocity is (velocity of sound=332m/s)

    Weightlessness produced in a space ship is due to:
    absence of inertia
    absence of gravity due to earth
    absence of accelerating force
    free fall of the spaceship

    The answer is freefall of the spaceship.
    the space ship is falling freely towards earth.
    the gravitational force is also experienced outside the earth.

  5. admin says:

    The spaceship in question is not falling freely towards earth!! By a spaceship it is meant that the ship is in space and weightlessness is felt in space as the gravitational attraction does not work there. The answer given is Right.

    plzzzzzzzzzz tell some very imp questions

  7. apeksha says:

    plzzzzzzzzzzzzzzzzzz admin tell those questions which come every year n can come tomorrow

  8. admin says:

    Apeksha, it is not possible to say the probable questions. If you can answer the questions that are there in our site and in the forum, you should be confident enough for the exam.
