by surface tension‚ makes a barometer using a very small glass tube‚ having a diameter d = 1.45mm‚ in order to save on the amount of mercury he needs. He reads the barometric pressure to be 7 519 mm Hg. a) W hat is the corresponding pressure in Pascal? b) W hat is the pressure after correction for the meniscus effect? (σ = 0.478 N/m‚ θcontact = 1390) 5- A vertical‚ clean‚ glass piezometer tube has an inside diamet er of 0.77 mm. When a pressure is applied‚ water at 330 C rises into the tube

Visual Basic was released in 1991 by Microsoft to compete with other popular programming languages such as C‚ C++ and Pascal. It was until version 3.0 when Visual Basic became the hottest programming language on the Market. Visual Basics provided tools which make programming much simpler that writing code in other languages. With these tools it cut programming time down

The prospectus for the second HOPL conference stipulated that to be considered "preliminary ideas about the language [should have been] documented by 1982 and the language .. in use or being taught by 1985."

The existence of God has always been a commonly asked question in the world today. Since there is no scientifically proven answer‚ arguments have been accumulated over time. One being the Pascal Wager’s argument. This theory states that either God exists or God does not exist‚ you can either wager for God or wager against God. This belief advocates the belief in God rather than providing evidence. Does Pascal’s Wager commit the fallacy of appealing to consequences? Each individual mental processes

It is also known as the figurate triangle‚ the combinatorial triangle‚ and the binomial triangle. Even though Pascal’s Triangle is named after seventeenth century mathematician‚ Blaise Pascal‚ several other mathematicians knew about and applied their knowledge of the triangle hundreds of years before the birth of Pascal in 1623. The Arabs‚ Persians and the Chinese discovered Pascal’s triangle in earlier centuries. The earliest depictions of a triangle of binomial coefficients occur in the tenth

smaller. 4) what is the difference between force and pressure? Force is the pressure applied to an object. Pressure is moved when something moves. 5) what’s is the SI unit of pressure‚ and how is it defined? The SI unit for for pressure is Pascal. Pa‚ which is the force of one newton applied over an area of one square meter. 6) how does the kinetic-molecular theory explain the pressure exerted by the gasses? The kinetic-molecular theory states that the pressure exerted by a gas is a
