Ready made notes for those who need it! Two people stand a distance of around 100m apart. The distance between them is measured using a trundle wheel. One of the people has two wooden blocks, which he bangs together above his head. The second person has a stopwatch which he starts when he sees the first person banging the blocks together and stops when he hears the sound. This is then repeated several times and an average value is taken for the time. The speed of sound can then be calculated using the equation that links speed, distance, and time. A person stands about 50m away from a wall (or cliff). This distance is measured using a trundle wheel. The person claps two wooden blocks together and listens for the echo. The person then starts to clap the blocks together repeatedly, in rhythm with the echoes. A second person has a stopwatch and starts timing when he hears one of the claps and stops timing 20 claps later. The process is then repeated and an average time calculated. The distance travelled by the sound between each clap and echo will be (2 x 50) m. The total distance travelled by sound during the 20 claps will be (20 x 2 x 50) m. The speed of sound can be calculated from this distance and the time using the equation that links speed, distance, and time.
noice mate you did really well i cant see my book because im partially blind so i listened to your voice and all my answers were cleared, you must be dumbledore
Mathematics is the class where we used to learn what is tools(calculus ,plus ,minus ,algebra) Thier we only see the tools and how to use the tools Phisics is the class where we use the tools and build usefulthings(like using calculus in kinematics to find daily useful things like velocity acceleration ect)
The speed of sound in imperial measurement is one thousand 0866 feet per second The cosine for thirty degrees is .point eight six six. When a sound wave travels seventy five feet is resounds. We call this resound an echo. When that happens it makes an harmonic in the space the sound came from. An harmonic is hexagonal. It has six sides. They measure six times one and six sides the square root of three. The haxagon has one cosine that is point five and one that is the square root of point seven five. The arcs cross at about one tenth of the radius of the circle that is made by the wave.. These points are known as nodes. In a solid body a node will move to its nearest whole number in physics this is called an harmonic. If we divide the square root of point seven five by ten we have point 0 eight six six. That is: one tenth of cosine thirty degrees. Tangent one tenth gives an angle. when we deduct that angle from ninety degrees we have an angle that has a tangent of ten. If we divide one by the cosine we have from tangent point one we have the cosecant. In this case, it is one point 0 one. ten times one point 0 one is ten point 0 one. In the case of this equation we used the cosine of thirty degrees to divide cosine thirty degrees divided by ten. So: ten times the square root of point 75 that is cosine thirty degrees is the square root of 75.The square root of 75 times the square root of one point 0 one equals the square root of seventy five point seven five. We can see if we draw this the co ordinade of a hexagon are the same as the speed of sound in feet per second is the same as the co ordinates of a hexagon. The social significance of this is we are looking at one of the co ordinates of 'Noah's Ark' That is Knowers arc.
I just described the co ordinates of a hexagon and how they relate to sound. It also has a significance with the placing of the cities on the world map. For example .6 divided by the square root of .75, from the hexagon gives the square root of .48, which as a cosine gives the angle from here to Mecca from the given meridian. I did not expect anyone to reply to my comment because it has trigonometry in it.
It is not the best method to measure the speed of sound, but it's a required practical for GCSE. A better method would be to use two microphones and an oscilloscope.
