2 A student investigаted hоw the frequency оf vibrаtiоn of а string varies with the tension in the string. The student connected masses to one end of the string and attached the other end to a vibrator as shown. See addendum Question 2 A signal generator was connected to the vibrator. The signal generator was adjusted until a stationary wave was produced on the string. The stationary wave had nodes at both ends of the vibrating length of the string, L, and an antinode in the middle. (a) Explain how nodes and antinodes are created on a string. (3) (b) The student changed the weight W applied to the string and adjusted the frequency f of the signal generator until the same stationary wave was set up on the string. The student plotted a graph of f2 against W. Explain why the graph was a straight line through the origin. (5) (c) Describe a method that can be used to confirm that the frequency value stated on the signal generator is correct. (2) (d) When W is 80.0 N, f is 659 Hz. Calculate the mass per unit length of the string. length L = 0.328 m (3) (Total for question 2 = 13 marks)

In the clаssicаl versiоn оf utilitаrianism theоry, J.S. Mill was the philosopher that focused on the quantity of the pleasure (i.e., simply how many units of pleasure/happiness), and J. Bentham was the philosopher who also took into account the quality (type) of the pleasure produced (i.e. intellectual pleasures versus sensual ones) when assigning the number of units of pleasure from each activity.
