Document Summary
Nb: mark values are given in brackets [ ] beside each problem. Write all your answers on the quiz paper. T = 2 l x = a cos( t + ) Wave speed: v = f where = k/m = 2 /t. In simple harmonic motion of a mass+spring system, the mass"s acceleration is. 1. proportional to its: (a) velocity. (b) frequency. (c) amplitude. (d) displacement. (e) all of the above. [4] at position a within a tube containing a compressible uid that is moving with steady laminar ow, the speed of the uid is 12. 0 m/s and the tube has a diameter 12. 00 cm. At position b, the speed of the uid is 18. 0 m/s and the tube has a diameter 6. 00 cm. What is the ratio of the density of the uid at position a to the density of the uid at position b: [3] you are originally 1. 0 m beneath the surface of a pool.
