point in a fluid has the same magnitude in all directions. (Pressure is a scalar) Variation of Pressure with Depth It will come as no surprise to you that pressure in a fluid at rest does not change in the horizontal direction. This can be shown easily by considering a thin horizontal layer of fluid and doing a force balance in any horizontal direction. However‚ this is not the case in the vertical direction in a gravity field. Pressure in a fluid increases with depth because more fluid rests on

joints‚ which means that they have a cavity in the joints that contains synovial fluid. Joints are not just made of bone‚ because if they were‚ friction would keep them from moving smoothly. The body uses cartilage and the synovial fluid to reduce friction in joints. Osteoarthritis happens when cartilage wears away over time and exposes bone to bone and increases friction‚ which is very painful. Synovial fluid is a fluid-like material that is present in many of the joints of the body. It serves the

In the story “Gryphon” by Charles Baxter‚ a 4th grade class has a weird sub‚ because their teacher Mr. Hebler got sick. Miss.Ferenczi the sub that tells all these weird stories to the students‚ although no one actually believes her‚ but a boy named Tommy does. Tommy defends Miss. Ferenczi stories a boy named Carl and other kids because he likes Miss. Ferenczi because she’s strange and tommy does not get to see things that are mysteries because Five Oaks is not.

Absolute entropy is entropy calculated relative to the absolute reference point determined by the third law of thermodynamics. Absolute humidity (specific humidity or humidity ratio) is the mass of water vapor present in a unit mass of dry air; that is‚ it is the ratio of the mass of water vapor to the mass of dry air in atmospheric air. Absolute pressure is the actual pressure at a given position and it is measured relative to absolute vacuum (i.e.‚ absolute zero pressure). Throughout this

P4 – Explain the role of the kidney in the homeostatic control of fluid balance Homeostasis is how our body works to keep the internal environment constant. The kidneys play a role in the control of fluid balance. For this assignment I will be discussing the gross anatomy of the renal system and the kidney. Renal System The renal system is a group of organs that work together to produce‚ store‚ and release urine. It consists of 2 kidneys‚ ureters‚ the urinary bladder‚ urethra and renal vessels which

* Formula One racing is one of the most revered sports in the world. In the auto-racing world it is second to none in class‚ prestige‚ history‚ and skill. The level of competition is immense and the window of entry is miniscule. This brings up one question: (what is the question?) Formula One racing’s history dates back to the 1950s when racecars were simple front engine‚ drum brake cars. Compared to the cars of today‚ they are dinosaurs‚ but they were the best of their time and a wonder to many
