Experiment 7: Velocity of Sound Jaybee J. Balilea‚ Sharmaine O. Baysic‚ Maria Anjelette Patricia C. Belen‚ Dianne Grace D. Bolloso Department of Biological Sciences College of Science‚ University of Santo Tomas Espana‚ Manila Abstract Sound is a mechanical wave that is an oscillation of pressure transmitted through a solid‚ liquid‚ or gas‚ composed of frequencies within the range of hearing and of a level sufficiently strong to be heard. It is produced when something vibrates causing

Task question In my task question I am going to study why does the velocity vary downstream? To carry out this investigation we will be going to Carding Mill valley; carding mill valley is located near the border of Wales‚ North West England in Shropshire. (This can be seen on image 1) (Image 1) (Image 1) This means we are collecting primary data which is mainly so we can get accurate and reliable set of results. In order to answer the task question

At the beginning of a cell phone contract‚ a cellular phone is sold with a wireless service that will generate cash for the service provider for the length of the contract; making Velocity Cellular Service multiple deliverables. Power Starterpack compromises of a single deliverable because the only service it is providing

shows that the motion is non uniform. The car is not travelling at a constant velocity as the graph is not a straight line. A straight line graph would indicate that the motion is uniform as the position increase is constant throughout. However‚ the graph of the toy car is a curve that becomes steeper as the time increases. This suggests that the motion increases more and more as time passes‚ showing that the velocity is increased each second. As the car is also moving in the positive direction‚

the graph on the right‚ line one is a line moving at a slower velocity compared to line 2 which is moving at a faster velocity in the same about time. There is a small error in this experiment‚ as you can see in the graph of the right‚ the velocity is not as constant. 5. What is the definition of velocity? Velocity is a vector quantity that has the same direction as the displacement. Displacement per unit time is called Velocity. 6. What did you have to do to

and time. Motion is the action of changing position. The aspects of motion are time‚ position‚ displacement‚ velocity and acceleration. Newton has described objects in motion in balanced and unbalanced state. There is equilibrium to the object with balanced forces that are acting on it. He said that the object will never accelerate if there will be no net force acting on it. Thus‚ the velocity is constant and its acceleration is always zero. In the Second Law of Motion‚ he showed that an object will

Graphical analysis of human motion‚ where displacement vs. time and velocity vs. time were graphed. Graphical analysis of motion where in the 10th seconds the total displacement is 6.31m‚ average velocity is 0.628 m/s and instantaneous velocity is 1.257m/s.
