Figure 1 Electric whisk Beater [o[1].[4| Give two energy stores that increase when the whisk is switched on. [2 marks] MIN IB/M/Jun24/8464/P/1H [o[1 [4] [o[1 [5] 04 Do not write outside the Use the Physics Equations Sheet to answer questions 01.4 and 01.5. box Which equation links current (2), power (P) and resistance (R)? [1 mark] Tick (“) one box. I P= P=IR P P=R P=PR The current in the whisk is 500 mA. The resistance of the whisk is 640 Q. Calculate the power of the whisk. [3 marks] Power = WwW IB/M/Jun24/8464/P/1H Do not write outside the The whisk has several settings that allow the beater to spin at different speeds. box A faster beater speed needs a greater power input from the mains electricity supply. [o[1].[6 | Whatis the potential difference between the live wire and neutral wire in the mains electricity supply? [1 mark] Vv Changing the beater speed does not change the potential difference between the live wire and neutral wire. The power input to the whisk changes because the current in the whisk changes. Complete the sentence. [1 mark] When the beater speed increases, the current in the whisk increases because the resistance of the whisk Turn over for the next question Turn over > 05 IB/M/Jun24/8464/P/1H Do not write outside the Last century, scientists used evidence from the alpha particle scattering experiment to box develop a new model of the atom. In the experiment, alpha particles were directed towards a piece of gold foil. [o[2].[1] What does an alpha particle consist of? [1 mark] [0[2].[2] Agold atom has the symbol TAU. How many neutrons are there in this gold atom? [1 mark] Number of neutrons = Question 2 continues on the next page Turn over > IB/M/Jun24/8464/P/1H 07 [3] The alpha particle scattering experiment led to the plum pudding model of the atom being replaced by the nuclear model. Figure 2 shows the results predicted by the plum pudding model and the actual results from the alpha particle scattering experiment. Figure 2 Results predicted by plum pudding model Gold foil — All particles undeflected Alpha source Actual results from the experiment Some particles slightly deflected Most particles undeflected Atiny proportion of particles deflected through large angles IMA IB/M/Jun24/8464/P/1H Do not write outside the box 10 Do not write outside the A student investigated how the current in a red LED varies with the potential bok difference across the LED. Figure 3 shows an incomplete diagram of the circuit used.

[2 marks] [o[3].[5| A second student did the investigation using a blue LED. The results for both the red LED and the blue LED showed the same pattern. What conclusion can be made about the investigation? [1 mark] Tick (W) one box. The investigation is repeatable. The investigation is reproducible. The results were accurate. Question 3 continues on the next page Turn over > 13 IB/M/Jun24/8464/P/1H 14 [o[3].[6| The relationship between current and potential difference for an LED is non-linear. 14 Which of the following always shows a linear relationship between current and potential difference?

The change in gravitational potential energy of the drone during the fall to this lower height was 3920 J. The mass of the drone is 2.5 kg. gravitational field strength = 9.8 N/kg Calculate the height above the ground of the drone when the motor was switched back on. Use the Physics Equations Sheet.
