Measuring the Speed of Sound (Moving Tube) KEY Purpose: To measure the speed of sound in air using a variable length column of air. Apparatus: resonance-tube apparatus (an open ended tube which can be moved in and out of a container of water) constant frequency source (tuning fork or computer generated tone) rubber hammer meter stick rubber stopper Procedure: 1. Set Up the Experiment: Place the open ended tube into the water‚ and verify that it can produce a resonance tube

13 References: 14 BACKGROUND The improvement of service delivery speed processes plays a key role in the overall competitiveness of modern service organizations. For example‚ Roth and Jackson (1995) provide clear evidence that process capability and execution are major drivers of performance due to their impact on customer satisfaction and service quality. Traditional efficiency studies measure the service delivery speed of a firm by its ability to transform inputs to outputs. However‚ the

" Factors affecting the speed of sound in a medium" Type of the medium- The speed of sound is not always the same. Remember that sound is a vibration of kinetic energy passed from molecule to molecule. The closer the molecules are to each other and the tighter their bonds‚ the less time it takes for them to pass the sound to each other and the faster sound can travel. It is easier for sound waves to go through solids than through liquids because the molecules are closer together and more tightly

With this ticket I have learned that it is not okay to speed. You should always pay attention while driving no matter how experienced you are. You never know what could happen. There is no need to travel at a faster speed than the one that is set by the law. I have learned that you don’t need to rush to get places. You will get there eventually. I don’t need to be in such a hurry going places. Speeding does not help you get anywhere faster. All speeding does is increase your chances of injuries

ABSTRACT In this paper we are trying to utilize one such source. Electricity is generated by replacing the traditional speed breakers with some simple mechanism. As vehicles pass over the speed breakers‚ they spin the rollers which are connected

The speed of chemical reactions – class experiment By Julia Shuker Year 10 science – Miss Phillips – Term 2 – 2013 – Julia Shuker Aim The aim of the experiment was to investigate the factors that increased or decreased the speed of chemical reactions between two different chemical reactions. Hypothesis If certain factors‚ such as concentration‚ temperature‚ catalyst and surface area are increased then the reaction rate will also increase due to the particles

Samantha Mackey 13. 2nd hour PHYSICS LAB REPORT: SPEED OF SOUND Purpose: In this lab‚ we will be doing 3 major things: 1) Collecting and organizing data to obtain resonant points in a closed pipe‚ 2) measure the length of a closed-pipe resonator‚ and 3) analyze the data to determine the speed of sound. Procedure: 1. Fill the graduated cylinder nearly to the top with water‚ with a tall glass tube open at both ends (the water level with act as the closed end). 2. Determine
