Document Content and Description Below

Describe the motion of the player between 3.4 s and 3.6 s. [1 mark] *0* The force exerted on the player when she is tackled causes her to accelerate. box ... . Write down the equation which links acceleration (a), mass (m) and resultant force (F). [1 mark] . The player accelerates at 25 m/s2 when a resultant force of 1800 N acts on her. Calculate the mass of the player. [3 marks] Mass = kg . The tracking device sends data to a computer during the game. Suggest one advantage of the data being sent during the game. [1 mark] Turn over for the next question Turn over ► A student made water waves in a ripple tank. . Describe how the frequency and wavelength of the water waves in the ripple tank can be measured accurately. box [4 marks] The student recorded values for the frequency and the wavelength of waves in the ripple tank. Table 1 and Table 2 show the results. Table 1 Reading 1 2 3 Frequency in hertz 9.8 9.4 9.3 Table 2 Reading 1 2 3 Wavelength in cm 1.7 2.2 2.1 . Determine the mean wave speed. [4 marks] box Mean wave speed = m/s . What is the advantage of taking repeat readings and then calculating a mean? [1 mark] . The speed of the wave is affected by the depth of the water in the ripple tank. The deeper the water the faster the wave. Explain how the depth of the water affects the wavelength of the wave if the frequency is constant. [2 marks] Turn over ► 0 4 Figure 4 shows the magnetic field pattern around a permanent magnet. Figure 4 . Where is the magnetic field of the magnet the strongest? [1 mark] . How does Figure 4 show that the strength of the magnetic field is not the same at all places? [1 mark] [Show More]
