    Question

    Which of the following statement is correct?

    >I. Speed of sound in steel is more than the speed of sound in glass. II. Speed of sound in brass is more than helium.
    A Both I and II Correct Answer Incorrect Answer
    B Only I Correct Answer Incorrect Answer
    C Only II Correct Answer Incorrect Answer
    D Neither I nor II Correct Answer Incorrect Answer

    Solution

    Solids and liquids have higher mass densities (r) than gases. But the corresponding increase in both the modulus (B) of solids and liquids is much higher. The speed of the sound in Steel is 5941 (m s-1) The speed of the sound in Brass is 2,120 (m s-1) The speed of the sound in Helium is 965 (m s-1)
