1 Advanced Subsidiay GCE (H57) Advanced GCE (H557) Physics B (Advancing Physics) Data, Fomulae and Relationships Booklet The infomation in this booklet is fo the use of candidates following the Advanced Subsidiay GCE in Physics B (Advancing Physics) (H57) couse and Advanced GCE in Physics B (Advancing Physics) (H557) couse. Clean copies of this sheet must be available in the examination oom, and must be given up to the invigilato at the end of the examination. Copies of this sheet may be used fo teaching. This document consists of 8 pages. Instuctions to Exams Office/Invigilato Do not send this Data Sheet fo making; it should be etained in the cente o destoyed. OCR 06 A Level in Physics B (Advancing Physics)
