Pentagons don’t tessellate‚ and neither do octagons. They overlap or leave gaps. And‚ looking at the rules listed in the previous paragraph‚ it is obvious that they don’t tessellate. Three Dimensional Objects Rectangular prisms are quite honestly the easiest part of geometry. Their surface area and volume are simple to discover. You simple use the following equation: 2LW + 2HW + 2LH.

America’s Privacy The National Security Agency (NSA) is a federal program under the Department of Defense that has the primarily task of global monitoring‚ collection‚ decoding‚ translation and analysis of information and data for foreign intelligence and counterintelligence purposes‚ including surveillance of targeted individuals on U.S. soil. In the mid-1970s‚ the NSA was investigated for the first time by Congress. At that time‚ the order of the NSA was that is “would never direct it’s

Topic: Millikan Oil-Drop Experiment The Millikan Oil-Drop experiment was the first experiment to determine the charge of an electron. In 1909‚ Robert Millikan ultimately came up with a way to determine this charge through finding the minute electric charge on a droplet from an oil mist. Basically‚ Millikan started with an enclosed chamber that had two flat plates inside‚ one with a positive charge and one with a negative charge. The portion is split up by the positively charged plate so at the beginning

concentration of solute. The solute being measured must be colored and is determined based on the adsorption of light photons on a wavelength. The spectrophotometer uses a beam of light that strikes the diffraction grating that basically forms of prism of light. Then only a specific wavelength of light shines through the spectrophotometer and interacts with the solute. The light that continues past the solute hits the phototube. The spectrophotometer then digitally shows the amount of units that

light changed directions‚ while passing through the prisms. He worked with some of the most advanced glass makers of his day. He later found out that when using the prisms and angling them to gather light‚ it intensified and it would project outward. Fresnel’s greatest creation is a large object that resembles a beehive‚ and is on display at the National Museum of American History. The Fresnel lens is not just one lens but a number of prisms. The prisms turned the flames into beams making it easier for

Oscar Wilde was an author‚ poet‚ and playwright in late Victorian England. Wilde was known for his wit and exuberant style. His unconventional writing is what drew many to his work‚ and many of his plays were well received. He spent the last three years of his life in exile after being imprisoned for “gross indecency”‚ and died in Paris‚ France from Meningitis at the age of 46. Among his last work before his death is The Importance of Being Earnest‚ a play in which Oscar Wilde delves into different

In our lab‚ we were given the task of burning seven different salts and taking notes of what we observed. The different salts included Potassium chloride‚ Calcium chloride‚ Strontium chloride‚ Lithium chloride‚ Copper II chloride‚ Sodium Chloride‚ and Barium Chloride. Burning a pinch of each salt separately by holding a nichrome wire over a Bunsen burner‚ we found that each salt emitted a different color of light. For example‚ Potassium Chloride burnt a bright pink flame when burned‚ while Calcium
