    Section B: Structured questions[20 marks]

    Answer all questions in the spaces provided.

    1. 11

      A student measures the period of a pendulum. Timing 20 complete oscillations with a digital stopwatch gives 34.0 s.

      1. (a)

        Explain why timing 20 oscillations gives a more reliable value for the period than timing a single oscillation.

        [2]
      2. (b)

        Calculate the period of one oscillation.

        [1]
      3. (c)

        The student repeats the measurement and obtains 34.4 s. State what should be done with the two results, and give the period from your method.

        [2]
    2. 12

      A cyclist rides along a straight road. She accelerates uniformly from rest to 8.0 m/s in 4.0 s, cycles at 8.0 m/s for 20 s, then slows uniformly to a stop in 2.0 s.

      1. (a)

        Use the first section of her ride to determine her acceleration, in m/s².

        [2]
      2. (b)

        Use the last section of her ride to determine her deceleration, in m/s².

        [2]
      3. (c)

        Work out the total length of her ride, in metres.

        [3]
    3. 13

      A student determines the density of a glass ornament. The ornament has a mass of 234 g. A measuring cylinder contains 100 cm³ of water; with the ornament fully submerged, the level reads 190 cm³.

      1. (a)

        State the volume of the ornament.

        [1]
      2. (b)

        Use the mass and the volume to find the density of the glass, in g/cm³.

        [2]
      3. (c)

        The ornament is knocked against a tap and a chip breaks off. State and explain what happens to the density of the remaining glass.

        [2]
    4. 14

      A wooden cube of side 4.0 cm has a mass of 38 g. Water has a density of 1.0 g/cm³.

      1. (a)

        Calculate the density of the wood.

        [2]
      2. (b)

        Predict whether the cube floats on water, and justify your answer using the densities.
