Speed of Sound in Air By: James Chen Lab Partner: Jin Zhang and Jake Salpeter Phys 130‚ Lab section: EE11 TA: Khaled Elshamouty Date of lab: October 29‚ 2013 Introduction Sound is a longitudinal (compressional) wave caused by a vibrating source. In this experiment‚ we use standing sound waves created by the tuning forks to determine the speed of sound in air in a tube when it reaches different resonances. In this lab we focused primarily on using standing sound waves (compressional

We also can find that in all myths‚ a fearful character with mysterious atmosphere is necessary‚ such as Satan in Bible‚ Nian-sho (a year monster) in the Chinese-new-year-story‚ or Misshepeshu (a monster) in Track: “Even though she was good-looking‚ nobody dared to court her because it was clear that Misshepechu‚ the water man‚ the monster‚ wanted her for himself.

Air Resistance Lab G Luhman‚ Mary …. Abstract: The acceleration of objects dropped from about 2 meters was found in order to derive the Reynolds Number. The effect of changing weight‚ shape‚ and radius of the objects (balloons) were tested independently such that it would be clear under what criteria either laminar or turbulent air flow is prevalent. • Introduction The difference between two models‚ laminar and turbulent‚ of air resistance may seem trivial the difference is can be seen

from the original location. However‚ I don’t know where the shift will be‚ but according to the research done on types of mirage‚ I believe that there will be a downwards shift. This is a result of an inferior mirage due to the warmer air density underneath the cooler air. Originally‚ the light is expectedly traveling in a straight line. Due to the refraction and the temperature gradients‚ the light won’t be stable. Instead‚ the light will appear to be dancing‚ and the location will not be consistent

Pressure difference between area of high pressure and low pressure causes the air to flow. Air moves faster as the difference in pressure is getting bigger. So‚ breathing air into the lungs needs lower pressure at the lungs than in the air outside of body. To exhale‚ compared to the air we are breathing‚ the pressure at the lungs should be higher. In order to enlarge the chest cavity when inhalation occurs‚ the muscles between the ribs and diaphragm contract. The motion of inhalation causes the diaphragm

Dissolved oxygen enters water through the air and plant. Dissolved oxygen produce by the atmosphere and the process is called air saturation. The gasses a stable body of water with no stratification‚ dissolved oxygen will remain at 100% air saturation. 100% air saturation means that the water is holding as many dissolved gas molecules as it can in equilibrium. At equilibrium‚ the percentage of each gas in the water would be equivalent to the percentage of that gas in the atmosphere like its partial

Nobody is quintessential and we all need help with something in life‚ whether it involves a project for school‚ homework‚ a video or board game‚ on the other hand‚ even an activity or sport. For example‚ track is a sport which merely only a handful of people run. So obviously not everyone who joins will know how to do every event or any certain event they want to pursue. Not to mention‚ not everyone can start out of blocks correctly‚ yet not everyone is supposed to. All events have a certain craftsmanship
