Sound is a vibration that spreads across a medium (i.e.‚ air or water) as a mechanical longitudinal wave formed by pressure. A Mechanical longitudinal wave can also be called compression wave as it generates compressions and rarefaction when traveling through a medium. (Sound Is a Pressure Wave - Physics Classroom) The amplitude of a sound wave is the difference between the pressure of the undisturbed air and the maximum pressure caused by the wave. The Speed of sound deviates with the temperature

Convergent Plate Boundaries Convergent plate boundaries are locations where lithospheric plates are moving towards one another. The plate collisions that occur in these areas can produce earthquakes‚ volcanic activity and crustal deformation. Convergent Plate Boundary – Oceanic-Continental: When continental and oceanic plates collide the thinner and more dense oceanic plate is overridden by the thicker and less dense continental plate. The oceanic plate is forced down into the mantle in a process

Volleyball: The 5-1 Rotation Introduction A team’s success in volleyball is directly linked to each player’s ability to understand his or her position on the court. The 5-1 rotation—1 setter and 5 hitters—provides the greatest flexibility and consistency for a team’s offense and defense. The following document describes the basic serve-receive set-up and a basic defensive posture. The diagrams are only a starting point. In both serve-receive and defense‚ players should be able to adapt

have had my mind set on college volleyball since 6th grade. My grandmother made me tryout for my middle school team because she wanted to watch me do something she thought was interesting. At first‚ I dreaded it. I would always go home and complain to my parents about how awful it was. But‚ after playing for a couple months‚ it started to grow on me. I got a grasp on the concept of it and something just clicked. I have loved it ever since. In all my years of volleyball‚ there have been four very important

Women’s Volleyball team. In the 1980s‚ they had won the world championships five times‚ which helped the team become the symbol of strong will. But no one can win all the time‚ since 2004‚ the team had met the setback and 11 years later‚ the new team won the championship again. What an inspiring story. The women’s volleyball team is favored by everyone. In the TV‚ their matches will be showed‚ people will watch and yell for them. My parents told me that their idols were the women’s volleyball players

about how big of winners we were. I was done with moping. For seven minutes of my life‚ I had forgotten that I could do anything I set my mind to‚ and I had given up. The worst seven minutes of my volleyball career were those seven minutes in the third game of the final match at Brighton Volleyball Tournament. I had put my determination down to wallow in my disappointment. Disappointment needs to build determination. I had decided a long time ago that there were certain things in life that I

They are also used for work holding and inspection on the shop floor. In some shop work holding applications‚ the accuracy would not need to be to the level of lab or inspection gage blocks. V-blocks are precisely square‚ and the V-groove should be in the exact center of the block. The prime purpose of a V-block is to hold cylindrical
