I'm stuck on this assignment, I need help with Questions Part A 1-3, and Part B 4-6 please

7-5 QuickLab Investigating Mechanical Resonance Problem 8 Repeat step 7 three more times. Each time, lengthen How can we cause a pendulum to begin oscillating at its the thread of mass 2 by 10 cm. For your last trial, the thread of mass 2 should be 40.0 cm long. resonant frequency using a forced frequency? Part B Materials retort stands 9 Adjust the thread length of mass 2 so that it is as close to the thread length of mass 1 as possible. string thread 10 Make sure both masses are motionless. Pull back 2 identical masses (200 g each) and release mass 2. Note the amplitude of vibration that mass 1 achieves. string retort 11 Pull the retort stands farther apart and hold them thread stand there so the tension in the string is increased, and mass 2 the string is almost horizontal. two equal 12 Make sure both masses are motionless, then pull mass 1 masses back mass 2 and release it. Note the amplitude of vibration that mass 1 achieves. A Figure 7.47 Questions Procedure Part A Part A 1. At what thread length did mass 2 create the 1 Read the questions in the next column before doing maximum oscillation of mass 1? Explain why this happened, in terms of frequency. the lab. 2 2. At what thread length did mass 2 create the Set up the two retort stands about 75 cm apart. minimum oscillation of mass 1? Explain why this 3 Tie the string to both retort stands at the same height happened, in terms of frequency. (50.0 cm) on each stand, as shown in Figure 7.47. Clamp the ends of the string to the retort stands 3. Why did mass 1 have a large amplitude of vibration so they don't slip. The string should be taut. in only one case? 4 Pull the two retort stands farther apart if you need Part B to remove slack from the string. 4. What effect did increasing the tension on the string 5 Attach the thread to one mass and tie the other end have on the amplitude achieved by mass 1? to the string so that the distance from the mass to 5. Why did increasing the tension alter the maximum the string is 30 cm. This is mass 1. oscillation of mass 1? 6 Repeat step 5 for the second mass (mass 2) so that 6. Write a sentence describing the effect that increasing it has a length of 10 cm and is attached to the the tension had on the resonant amplitude of mass 1 string about 15 cm from the first mass Use the terms forced frequency and resonant amplitude 7 Make sure neither mass is moving, then pull mass 2 in your answer. back a small distance and release it. Observe the motion of mass 1 as mass 2 oscillates. Make a note e LAB of the maximum amplitude that mass 1 achieves. For a probeware lab, go to . ... www.pearsoned.ca/school/physicssource
