Pearson Edexcel Level 3 GCE Physics Advanced Subsidiary PAPER 2: Core Physics II. question booklet and mark scheme results 2022 SECTION A Answer ALL questions. All multiple choice questions must be... answered with a cross in the box for the correct answer from A to D. If you change your mind about an answer, put a line through the box and then mark your new answer with a cross . 1 Which of the following best describes the newton as used in physical measurements? A base quantity B base unit C derived quantity D derived unit Questions 2 and 3 refer to the following information. A ray of light, in air, is incident on the edge of a triangular glass prism as shown. The critical angle for a light ray meeting a glass to air boundary is 35°. A D C B 60° 2 Which path, A, B, C or D, will the ray follow? A B C D (Total for Question 2 = 1 mark) 3 Which of the following gives the value of the refractive index of the glass? A sin35 B 1 sin35 C sin−1 1 35   D 1 1 35 sin −1       (Total for Question 3 = 1 mark) Questions 4 and 5 refer to the following information. The speed v of a transverse wave on a string is given by v = Tμ where µ is the mass per unit length of the string and T is the tension in the string. 4 µ can be calculated from measurements of the mass and length of the string. The percentage uncertainty in the measurement of mass is 0.4%. The percentage uncertainty in the measurement of length is 0.05%. Which of the following is the percentage uncertainty in the calculated value for µ? A 0.4 + 0.05 B 0.4 − 0.05 C 0.4 × 0.05 D 0.4 ÷ 0.05 [Show More]
