Discussions:- I. Objective. To measure the speed of sound waves in air. ll. Abstract. This experiment tried to determine the speed of sound waves. To determine the speed‚ a resonance tube full of water was used and five different tuning forks of known frequency. Each fork was struck above the water level and the water level was slowly moved down until a resonance was heard. The distance where the resonance occurs were recorded and the speed of the waves

I will never ever speed again. Speeding cost way too much time and aggravation to continue speeding. This ticket has made me realize that all speeding does is put me and other people in danger and waste a lot of gas. And in these economic times wasting gas isn’t the best idea. I am unemployed and I’ve been trying to get a job to pay for this ticket so my parents wouldn’t have to. This is good because now I know that speeding is just wrong. I can drive 45 in a 45 and some one could be doing 60

the vibration of an object; once the item vibrates the sound waves then radiate outwards until they are either stopped or they die out. A sound wave has three characteristics: Frequency‚ amplitude and phase. These three allow us to measure pitch‚ speed and potentially the energy of the wave as well. Sound travels when particles interact with each other when a sound source effect the first particle of a medium. This then causes the particle to vibrate backwards and forwards which then means that

Many drivers these days would probably agree that there’s a “need for speed” on roadways everywhere. There’s always people running late for appointments‚ rebellious teen drivers‚ and fast sports cars who think they have the right to go faster than what the law prohibits. It’s not until they’re caught that they realize they’re no more important than the rest of the drivers on the road. Speeding is a very customary way for drivers to break the law. Breaking any law usually leads to unpleasant consequences

Dear Fellow Americans Over 10‚000 people died in speed related accidents in 2009 in the United States. Now let’s fast forward to 2013 when The National Safety Council estimated that 35‚200 people died in U.S traffic accidents; plus there were about 3.8 billion crash injuries requiring medical attention. An official from the agency blamed majority of it on human error (speeding). People disobey speed limits for some of the same reasons they break other laws. Its gives them a sense of power

all of physics." The deepest mystery in all of physics is that in a vacuum all bodies fall with the same constant acceleration. 2. In the next sequence‚ we see a person diving from a board and a leaf falling from a tree. It is stated that the speed of a falling body increases as it falls. If the statement concerning falling bodies is true‚ then why does the leaf seem to fall so much more slowly than the diver? The leaf seems to fall much more slowly because it has less mass then the diver which

Thiscontainer could be displaced vertically in order to change the water level. We would thenmake a tuning fork vibrate above the pipe and change the water level until the resonance wasat maximum intensity.Hypothesis: The

the two pulses. 3. (17P16) A rescue plane flies horizontally at a constant speed searching for a disabled boat. When the plane is directly above the boat‚ the boat’s crew blows a loud horn. By the time the plane’s sound detector receives the horn’s sound the plane has travelled a distance equal to half its altitude above the ocean. Assuming it takes the sound 2.00 s to reach the plane‚ determine (a) the speed of the plane and (b) its altitude. 4. (17P40) A block with a speaker bolted to

Writer’s Letter Initially when given this topic of “language‚” I was a little confused. I starred at the instructions for about an hour trying to brainstorm ideas. At first‚ I wanted to write about Theatre and the role that it has as a universal language across the world. Although there may be a language barrier between the actor and audience member‚ the scenery‚ costume‚ facial expressions‚ and movement help tell a story. However‚ I choose not to use this topic because it wasn’t very personal
