(e) (i) For a close tube, the wavelength at resonance for the n-th harmonic (where n is an odd integer, n=1, 3, 5, ...) is given by: = (4L)/(n) where L is the length of the tube. (ii) For an open tube, the wavelength at resonance for the n-th harmonic (where n is an integer, n=1, 2, 3, ...) is given by: = (2L)/(n) where L is the length of the tube. (a) (i) Two differences between a primary cell and a secondary cell: • A primary cell is non-rechargeable, while a secondary cell is rechargeable. • The chemical reactions in a primary cell are irreversible, whereas in a secondary cell, they are reversible. (ii) Two characteristics of an electromotive force (EMF): • EMF is the maximum potential difference across the terminals of a cell when no current is drawn from it (open circuit). • EMF is the work done per unit charge by the source in moving the charge around the complete circuit. (iii) Electrical symbols: I. Inductor: —[baseline=(current bounding box.center)] (0,0) sin (0.2,0.2) cos (0.4,0) sin (0.6,-0.2) cos (0.8,0) sin (1,0.2) cos (1.2,0);— II.
