extent that there is audible friction during the production of that sound. But in case of the production of vowels as there is no closure and no narrowing of the air passage to the extent that it may produce audible friction both articulatory and auditory terms are used to describe and classify them. In Phonetic terms vowels are speech sounds in the production of which there is no obstruction or closure and no narrowing of a degree that would cause audible friction in the pharynx and the mouth.

CHAPTER 1 INTRODUCTION The seismic force-resisting system of a building structure is composed of vertical elements‚ horizontal elements‚ and the foundation (Fig.1.1). The vertical elements extend between the foundation and the elevated levels‚ providing a continuous load path to transmit gravity and seismic forces from the upper levels to the foundation. The horizontal elements typically consist of diaphragms‚ including collectors. Diaphragms transmit inertial forces from the floor system to the

GAS DYNAMICS AND JET PROPULSION 1. What is the basic difference between compressible and incompressible fluid flow? Compressible 1. Fluid velocities are appreciable compared with the velocity of sound 2. Density is not constant 3. Compressibility factor is greater than one. 2. Write the steady flow energy equation for an adiabatic flow of air. In an adiabatic flow q = 0. Therefore energy equation becomes. 2 c12 c2 h1 + + gZ1 = h2 + + gZ 2 + Ws 2 2 Incompressible 1. Fluid velocities are small

slow down the initial acceleration‚ but the car would travel a longer distance due to increased momentum‚ which might overcome kinetic friction. Rationale: Some reasons of why that it was thought that the more weight added to the car would increase the overall distance travelled is because in order to stop the Lego car with an example of 40g in it‚ kinetic friction and the force of gravity will have to work harder to slow the car down‚ due to Newton’s law of motion. “Objects in motion tend to stay

Laura Cortez Science Per. D 11/28/12 Soccer Ball Lab I. INTRODUCTION Speed‚ distance‚ time‚ and acceleration are all very complex formulas that are interdependent. These formulas are measured in motion data and used to determine the final instantaneous speed‚ distance‚ time‚ and acceleration. Distance and time are two formulas that are used to determine speed and time. For example‚ distance equals speed multiplied with time given‚ time equals distance divided by speed‚ and speed is

Mousetrap Car Report What sources of friction (both good and bad) does one need to consider in designing an effective mouse trap car? Try to come up with at least four [4] Explain how Newton’s first‚ second and third laws apply to the performance of your car [3] First Law: An object in motion will stay in motion‚ and object at rest will stay at rest unless acted upon by an outside force. In other words‚ the mouse trap car will not move unless an outside force will cause it to move
