I need help with LABS 7-11 please

PERIOD MEASUREMENTS Time to Complete (Seconds) Number of Cycles Angle 10 24, 58 24,58 24.58 28, 38 17. 21 2.458 / 2.458 2.458 12. 838 1. 721 mark) LAB 7. Has the period changed as a result of changing the angle of release? Explain. mark) LAB 8. Has the period changed as a result of changing the mass? Explain. marks) LAB 9. Has the period changed as a result of changing the length of the pendulum? Explain. Explain. marks) LAB 10. Has the period changed as a result of changing the acceleration due to gravity? marks) LAB 11. Summarize your findings from LAB 7 to 10 by listing the parameters that do affect the period of the pendulum and the ones that do not have an effect
