66mm? 4- A student in freshman chemistry‚ who knows nothing about the correction due to the meniscus caused 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?

Saturn is the second largest planet in the Solar System‚ then Uranus‚ then Neptune‚ then Earth‚ then Venus‚ then Mars‚ and last Mercury. Even though Jupiter is so massive it rotates faster than Earth‚ which is the third closest planet to the Sun. Finally‚ you should know that Jupiter is the best planet in the Solar System. Would you believe that the storms on Jupiter last for

Reaction Paper Doomsday‚ Aliens‚ and Thoughts By Juliene Lindy Tiu The biblical theory that states God made the universe and the Big Bang Theory that says the cosmos was created through a massive explosion: these two are only some of the speculative theories as to how the universe was formed. Undoubtedly‚ there are a million more probable theories for this just like there are a million ways to kill a cat. It is just so ambiguous. I mean‚ how can we even know if any of our theories really do

planet-like moon‚ Titan has a diameter 50% larger than Earth’s natural satellite‚ the Moon‚ and is 80% more massive. It is the second-largest moon in the Solar System‚ after Jupiter’s moon Ganymede‚ and is larger by volume than the smallest planet‚ Mercury‚ although only 40% as massive. Discovered in 1655 by the Dutch astronomer Christiaan Huygens Titan was the first known moon of Saturn‚ and the fifth known satellite of another planet. Titan is primarily composed of water ice and rocky material.

motion. Ptolemy’s model‚ in part‚ sought to explain this behavior. The inferior planets were always observed to be near the sun‚ appearing only shortly before sunrise or shortly after sunset. To accommodate this‚ Ptolemy’s model fixed the motion of Mercury and Venus so that the line from the equant point to the center of the epicycle was always parallel to the earth-sun line. 17.

Effect of Iodine on mercury concentrations in dental-unit wastewater John Michael Panganiban and Ian Jasper Ocampo Objective: This study was undertaken to determine whether iodine used to control bacteria in dental unit wastewater could increase mercury concentrations in dental wastewater. Introduction: Two of the major concerns in dentistry are biofilm in dental unit waterlines and the contamination of dental unit wastewater with mercury. Biofilms are microscopic communities that consist

retinue of objects that orbit the Sun‚ most of the mass is contained within eight (8) relatively solitary planets whose orbits are almost circular and contained within a nearly-flat disc called the ecliptic plane. The four smaller inner planets; Mercury‚ Venus‚ Earth and Mars‚ also called the terrestrial planets‚ are primarily composed of rock and metal. The four outer planets‚ Jupiter‚ Saturn‚ Uranus and Neptune‚ also called the gas giants‚ are composed largely of hydrogen and helium and are far

Titan‚ is the only moon in the Solar System to possess an atmosphere. FACT NINE Saturn has such a low density (meaning that its particles are far apart) that‚ if there was an ocean big enough‚ Saturn would float on it. In comparison‚ Earth and Mercury would sink to the bottom quickest. FACT TEN A year on Saturn would take almost thirty Earth years. However‚ a day on Saturn is about 10 and a half
