Q1. A rectangular container measuring 32 cm 34 cm 51 cm is filled with water. What is the mass of this volume of water in kilograms and grams?

Q2. A stretched rubber band has the length of 0.13 m and a fundamental frequency of 440 Hz. What is the speed at which waves travel on the rubber band?

Q3. Three pendulums with strings of the same length and bobs of the same mass are pulled out to angles q1, q2 and q3 correspondingly and released. The approximation sin q = q holds for all three angles, with q3 > q2 > q1. How do angular frequencies of the three pendulums compare?
