**Chapter 16: PHYS 203: Fundamentals of Physics**

4. If you see a firecracker combust 900.0 m away and the temperature of the dry air is 30 °C, how long will it take for you to hear the combustion?

5. A woman is swimming when she hears the underwater sound wave from an exploding ship across the harbor. She immediately lifts her head out of the water. The sound wave from the explosion propagating through the air reaches her 4.50 s later. How far away is the ship? Assume the water temperature is 15 °C and the air is 20 °C.

6. What is the length of the brass pipe if you measure a sound wave to take 0.5 s to travel the length of the pipe?

7. If you double the period of a pendulum, quantitatively state what happens to the length of the pendulum.

8. If you measure the period of a pendulum on Earth to be 3.1 s and then were to measure the same pendulum on a different planet to be 5.2 s, what will be the second planet's gravitational pull?
