Low-pass filter

“What the hell was that?” Cartman demanded. I shrug my shoulders as I continue to find coffee grounds and a coffee filter. Opening one of the many cabinets, I automatically see junk food. A sigh escapes from me, and I filter through the contents, hoping that this cabinet might have one of the materials I need. “Coffee, coffee, where would coffee be?” I mumble to myself, hoping that just by mentioning it somehow it will magically show up. “If I help you get coffee, will you tell me what that…

magnetically susceptible material is extracted from a mixture depending on a magnetic force. Filtration is separation of an insoluble solid and a liquid. Filtration depends on solubility, the filtrate is the one want to keep (liquid) and the residue on the filter paper is the solid (we may or may not want to keep depending on the experiment). Evaporation is the separation of a liquid and a soluble liquid. In evaporation the solution is heated to the boiling point for the liquid to evaporate.…

When both solutions are mixed a white precipitate (Calcium Carbonate) is formed alongside Sodium Chloride. A clear colourless liquid is observed as the white precipitate is filtered through the filter paper.…

The gradual transformation in data quantity has resulted in emergence of the Big data and immense datasets that need to be stored. Traditional relational databases are facing many difficulties meeting the requirements of the volume and heterogeneity structure of big data. NoSQL databases are designed with a novel data management system that can handle and process huge volumes of data. NOSQL systems provide horizontal scalability by supporting horizontal data partitioning across heterogeneous…

A strip of magnesium (Mg) ribbon was cut with a scissor. Said piece had a length of 6 cm, and a weight of 0.071 g. The magnesium piece was rolled into a compact ribbon. After that, with copper turnings the mg piece was covered. Next, 700-mL of water was placed into a 1000-mL beaker. Then, the copper-wrapped magnesium was placed in the beaker. A 100-mL graduated cylinder was filled completely with water. After, said cylinder was covered with a small piece of paper towel over the entire rim, and…

be smaller than the other and also have a lid. We can’t forget the grinding tools, straining materials, and storage containers. A coffee grinder works perfect for grinding the plant matter. I like to use cheese cloth for primary straining, coffee filters for the final straining and mason jars for…

factor that affected the results obtained was that we used a folded paper instead of fluted filter paper. A fluted filter paper is preferred over a folded filter paper because it has more surface area and also helps the filtration to take place faster. Since we did not use the fluted filter paper during the filtration some solvent evaporated resulting in premature crystallization and the solute stayed on the filter paper along with the impurities, making the percent recovered lower. The melting…

Firefighters-from career veterans with twenty or more years, to volunteers with only a few months under their belts-go through intense, rigorous, and extremely important training. What could happen if firefighters just did the minimum amount of training required and that was all they trained? THE DENVER DRILL On 28 September 1992, in Denver Colorado, a three-alarm fire broke out. During attempts to locate and rescue survivors, Mark Langvardt, a 16-year veteran firefighter, was separated from…

complicated, but many are simple and would significantly improve level of play. One simple change that would significantly improve quality of play is changing the pass-interference rule. Pass interference is is a foul that occurs when a player interferes with an eligible receiver's ability to make a fair attempt to catch a forward pass. The penalty is overcalled, abused by teams and has negatively influenced the outcomes of many games. This year has been especially bad. Teams have gradually…

My business which would be called the FF Facial Defense. This company would be designing a better SCBA, Self Containing Breathing Apparatus, face mask and would be located in the state of Pennsylvania As a firefighter I have seen turn out gear that was able to withstand up to five hundred degrees for five minutes or 1,200 degrees of heat for 8 minutes. However, I have learn from my fire academy instructor and from pictures that our face mask is not able to withstand 450 degrees of heat, but…
