A bus topology is the minimum complex network configuration it creates use of a single transmission medium called a coaxial cable. The star topology consists of shielded twisted pair wire (STP) or unshielded twisted pair wires (UTP). Due to the high cost of STP wire‚ most networks use UTP‚ however‚ STP wire must be used if the distance between the hub and the node beat 110m. In most examples the cable is many different lengths joined by a T-connector which allows the cable to divide into various

moles-stoichiometry-practice-problems Now you’re ready to use what you know about conversion factors to solve some stoichiometric problems in chemistry. Almost all stoichiometric problems can be solved in just four simple steps: 1.Balance the equation. 2.Convert units of a given substance to moles. 3.Using the mole ratio‚ calculate the moles of substance yielded by the reaction. 4.Convert moles of wanted substance to desired units. These "simple" steps probably look complicated at first

" a Home Depot spokeswoman said of China. Mattel Inc. shut its Chinabased Barbie flagship store in March of last year after it learned that Chinese parents would rather have their children read books than take a doll for a spin in her plastic Corvette. Best Buy Co. closed its nine China outlets in February 2011 after discovering that Chinese consumers needed washing machines and air conditioners more than espresso makers and stateoftheart surround sound stereo systems. A spokeswoman for Mattel said the toy company is still selling Barbie in China

Introduction The objective of this experiment is to combine Magnesium (Mg) with hydrochloric acid (HCl) to determine the molar volume of hydrogen gas (H2) (converted to the molar volume at STP) and then‚ to compare obtained results with the molar volume of an ideal gas. To determine the measured molar volume of hydrogen gas‚ we are going to use this equation: The molar volume of the ideal gas will be determined by the equation ‚ where T = 237 K‚ P = 101.3 kPa. The hydrogen gas will be collected

STP most often refers to the 150 ohm IBM Type 1‚ 2‚ 6‚ 8‚ and 9 cables used with Token Ring networks. Unlike UTP cabling‚ the pairs in STP cable have an individual shield‚ and the individual shielded cables are wrapped in an overall shield. The primary advantages of STP cable are that it has less attenuation at higher frequencies and is less susceptible to EMI. Since the advent of standards-based structured wiring‚ STP cable is rarely used in the United States
