Learners interpret a circuit used to study how wire length affects resistance, identify measuring instruments, assess precision, and justify repeating trials and calculating a mean. The paper requires linking current, potential difference and resistance, working out resistance from given values, naming graph axes, and drawing conclusions from plotted data. It also covers radium-226 decay, determining half-life and explaining radiation hazards across distance, plus questions on isotopes of sodium.","Please write clearly in block capitals.  \nCentre number  \n\n|  |  |  |  |  |\n| --- | --- | --- | --- | --- |\n\nCandidate number  \n\n|  |  |  |  |\n| --- | --- | --- | --- |\n\nSurname    \nForename(s)    \nCandidate signature    \nGCSE  \nCOMBINED SCIENCE: TRILOGY  \nHigher Tier Physics Paper 1H  \nH  \nSpecimen 2018 (set 2) Time allowed: 1 hour 15 minutes  \nMaterials  \nFor this paper you must have:  \n􀁸 a ruler  \n􀁸 a scientific calculator  \n􀁸 the Physics Equations Sheet (enclosed) .  \nInstructions  \n􀁸 Use black ink or black ball-point pen.  \n􀁸 Fill in the boxes at the top of this page.  \n􀁸 Answer all questions in the spaces provided.  \n􀁸 Do all rough work in this book.
