Objective: Demonstrate the relationship between inertia and mass. Materials: Three identical plastic bottles, water, bandana, 11 and a sturdy table Procedures:
1. Label the three plastic bottles A, B, and C.
2. Fill Bottle A with water up to the brim, half-fill bottle B. and leave bottle C empty.
3. Cover the surface of a sturdy table using the bandana and stand the bottles on top of it.
4. Quickly pull the bandana off the table and observe what will happen.

Guide questions: Read and answer the following questions in your answer sheet.

1. When you pull the bandana off the table, which bottle tipped off?

2. Which bottle is the sturdiest and did not move much?

3. which of the three bottles has the greatest mass than the rest?

4. which bottle has the greatest inertia?

5. based on this activity, how can you relate the inertia of the bottle with it's mass?

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light

Water flows through a garden hose which is attached to a nozzle. the water flows through hose with a speed of 2.19 m/s and through the nozzle with a speed of 19.8 m/s. calculate the maximum height (in m) to which water could be squirted if it emerges from the nozzle and emerges with the nozzle removed.
