The value of each question is noted in the left margin in parentheses. 1. You will be conducting an online lab for this question. Follow the steps to answer parts a-i. Open the PheT "Pendulum Lab" lab by typing the following link into your web browser: bit.ly/2xAj&KG ii. Select the "Lab" option. iii. Select the "Period Timer" option to insert a period timer. iv. Adjust the length of the pendulum to 0.10 m. V . Drag the mass to an angle of 10 and release it. vi. Use the period timer to measure the period of your pendulum. vii. Record your answer in the table below. vili. Repeat for each of the lengths in the table, always releasing the pendulum 2 from 10. a) Record your period measurements below: Length (m) Period (s) 0.10 (2) 0.30 0.50 0.70 3 0.90 ENG 12:39 AM US 2024-06-08C Home - Learr X Google Dich x | G L/X - Tim tren x | \\ SCN2797-15( X 5 Assignment1 X Course Hero * *Course Hero X Dashboard x C h) What can | x | + X C vvs-moodle.pembinahills.ca/pluginfile.php/1153728/mod_resource/content/1/Assignment18_Physics20.pdf E Assignment18_Physics20.pdf 2 / 5 | . 67% + Physics 20: Mrs. Tyler Assignment 18 b) Choose a length from the table in part a and calculate the theoretical period of a pendulum with that length. Answer to 4 significant digits. Compare it to the measured value in part a. Provide one reason for why your theoretical value might not exactly match the experimental value. (2) c) Us physicists like linear data. We know that the length and period of a 2 pendulum do not exhibit a linear relationship since they are not directly proportional. However, we can manipulate our data to create a linear relationship. Fill in the table below by squaring your experimental values for the periods.

Show all your work and answer to three significant digits. (1) 2 f) An equation from your formula sheet can be manipulated to isolate T?/1, the value you found in part e. Show how this can be done. (2) 3 g) Substitute your value from part e into your equation from part f to calculate the gravitational field strength/acceleration due to gravity.

(2) 2 The mass is pulled aside to a height of 35.0 cm above its equilibrium position and released. The pendulum whistles with an emitted frequency of 19.9 Hz, which is below the audible frequency range of a human ear. But you can hear the pendulum as it approaches you. What is the apparent frequency of the 3 whistle as it swings at its maximum speed towards you (in the gravitational field found above)? Assume the speed of sound is 343 m/s. (3) You're done!
