can you please help me with this assignment, please show all the work.

This is Physics 20 (grade 11)- UNIT D PROJECT

Part 1: Weighted Spring Calculations

Question 1 An object suspended from a spring with a spring constant of 2.56 N/m vibrates with a Not yet answered frequency of 0.148 Hz. Marked out of 2.00 What is the mass of the object? Flag question kg (Round your answer to 2 decimal places) What will be the acceleration of the object at a displacement of -0.120 m from the equilibrium position? m/s2 (Round your answer to 3 decimal places.) Question 2 Please type or upload pictures of all the work done to determine the mass and acceleration Not yet answered of the hanging object. Marked out of You will not receive partial marks for this question unless you show all your work. 2.00 Flag question Paragraph BQuestion 3 A 0.250 kg mass is suspended from a string, forming a pendulum. What length of Not yet answered string would be needed so that the pendulum oscillates at 0.148 Hz? Marked out of m (round your answer to 1 decimal place) 3.00 Flag question What would be the magnitude of the restoring force on the pendulum at an angle of 6.24 from the equilibrium position? N The pendulum is pulled aside until it is 0.386 m above its lowest position and released. The pendulum is designed to emit sound waves at a frequency of 440 Hz; however, as it swings toward and away from an observer, the frequency appears to vary slightly. What would be the apparent frequency of the sound from the pendulum as it swings at its maximum speed toward an observer? Assume the speed of sound is 345 m/s. HzQuestion 4 Please type or upload pictures of all your written work regarding the pendulum calculations. Not yet answered You will not receive partial marks for this assignment unless you show all your work. Marked out of 3.00 Paragraph B Flag
