Document Summary
Questions from part a and part b and 1 out of two from part c: questions from part a are 2 marks each (total 20). Questions from parts b and c are 10 marks each (total 80: relax! Please use three significant figures in all calculations. Part a(total 20 marks: a simple harmonic oscillator with amplitude a has a period of 4. 00 seconds. The density of the object is: 667 kg/m3, 1500 kg/m3, 333 kg/m3, 1000 kg/m3, a string fixed at both ends is oscillating in its third harmonic. Along the length of the string there are two antinodes three antinodes: one antinode, four antinode, a source (s) and an observer (o) are moving in the same direction with the source following the observer. Put the correct signs into the doppler equation. f. 0: two charges of equal magnitude, one positive and the other negative, are at the same position in an electric field.
