number 6 please

Answe Number the answers correctly according to the number QUESTION 2.1 question paper. GAIE line between two sub questions, for example betwoon Limpopo DOE/FEB 2022 Physical Sciences P1 A group of Grade 12 Inamers in Vhembe West District perform an experiment to verify the law of conservation of linear momentum, in a school laboratory. They use three IDENTICAL dynamics trolleys A, B, and C. each of mass 2 kg. the trolley's are arranged on a horizontal Frictionings tract/runway (2000 mm long) between two fixed buffers/planks/barriers, as shown in the diagram below. 2000 mm Trigger 250 mm 250 mm Trolley A 's spring is released to allow the trolleys to move apart. The learners repeat the procedure until a point Y is found on the runaway such that, when the spring is released, the trolleys reach the buffers/planks/barriers P, and Pa, simultaneously (at the same time). For this investigation, write down the following: 1 .1 . A suitable investigative question 1.2 The dependent variable 1.3 The control variable 1.4. The independent variable Formulate the hypothesis for this investigation. Suggest a reason why the experiment must be repeated at least three times. It is advisable to perform this experiment in groups NOT as individuals. State ONE advantage for the group work in this case Which distance represents the velocity of: 5.1. Trolley A? (X1 or X2) 5.2. The combination of trolleys B and C? (X3 or X4) Calculate the expected magnitude of the displacement of: 6.1. Trolley A 6.2. The combination of trolleys B and C. Vhembe West Please turn o
