AQA A Level PHYSICS (7408/3A) Paper 3 Section A Question Paper & Mark scheme (Merged) June 2023 [VERIFIED] A stroboscope emits bright flashes of white light. The duration of each flash and the frequency of the flashes can be varied. Table 1 shows information about the stroboscope. Table 1 Minimum Maximum Duration of each flash / μs 60 300 Frequency of flashes / Hz 1 150 The duration of each flash is T1. The time from the start of a flash to the start of the next flash is T2. The duty c...

How do you avoid parallax error? correct answers Look perpendicularly at the ruler Which meniscus do you use when measuring volume? correct answers Bottom meniscus (except Mercury - upper meniscus) How do you measure short intervals of time? correct answers Time a specific number of cycles and then divide the total time by the number of cycles. Mass correct answers The amount of matter and object is made up of OR the property of an object that resists changes in motion Density correc...

How do you tell if a graph has negative edges? - ANSWER-when fitting graph on a table, if the number of moves decreases the w() from edge to edge, then there is a negative edge; check from 1 to n Why are all pairs Dist(y,z) n^2? - ANSWER-Because it builds a two dim table! What is the run time of bellman ford algorithm? How about if you had to do it for all edges? - ANSWER-O(nm) O(n^2m) Floyd-Warshall run time? - ANSWER-O(n^3) What is the base case for the bellman ford algorithm? - ANSWE...
