Abstract The average density of four separate pieces of polypropolene was determined to be 0.867g/cm3. Given the average densities of six different known plastics, we were able to identify the unknown plastic as PVC by its density. Made-to-order essay as fast as you need it...
Tunable RF filters are commonly used in various lab environments for testing many frequency bands that include WiFi, UHF, PMR, Tetra, PCS and LTE. Tunable notch filters or band-rejection filters are an excellent solution for band selection or frequency discrimination with high attenuation greater than...

Energy is one of the most concerning issue of the world. It is necessary to develop energy technology that is clean, sustainable and affordable to produce. Currently more than 85% of energy is produced from fossil fuels, which will be exhausted in some time, which...
Thyristor is a type of diode that allows current to flow if and only if a control voltage is applied to its gate terminal. This kind of diode has three electrodes namely anode, cathode and gate. Thyristors have different working principle depending on its classification....
Most modern-day electricity is elsewise known as secondary energy, meaning that it is a combination of fossil fuels, nuclear fuel, and renewable energy. Renewable energy sources include, wind, hydro, solar, and geothermal (2 Sharif). Fossil fuels, cause a substantial amount of pollution, which in turn...
People whose origins include the keffiyeh in their history, tradition and culture, and people who are attached to their history and refuse new ideas and “updates” on society’s beliefs might find it hard to accept that the Keffiyeh’s use, like many other things in this...
Currently, in everyday life, fossil fuels are the world’s primary energy source. It is formed over millions of years from organic materials (remains of dead animals and plants) and is mostly used to power vehicles and generate electricity. Types of fossil fuels includes coal, oil,...
Electrical resistivity is a fundamental property that quantifies how strongly a given material opposes. Resistivity is measured by ohmsO. Electrons often encounter semi or non-conductive materials which causes resistance. A low resistivity indicates a material that readily allows the flow of electric current. Electrical conductivity...
We all know that Momentum means inertia in motion. It is the product of the mass and the velocity of an object (Momentum = mass x velocity). Therefore, in shorthand notation, Momentum= mv. A moving object can have a large momentum when either it mass...
The reason as to why we should not support radioactive waste is because it pollutes the environment and reduces tourism Varies from low level waste to high level waste.Also known as nuclear waste.It is divided into three categories; high, low, `and intermediate level waste.Low level...
It’s like something out of a science fiction movie. Nuclear waste – hundreds of millions of gallons of it – are buried underground after the Cold War. Years later, it threatens to contaminate major sources of food and water for an entire nation. The government...

An action potential is an electrical impulse that begins at the axon hillock (trigger zone), propagates away from the soma, and moves down the axon, synaptic knob, and synapse. The action potential is triggered by a depolarization of the neuron from -70mV to -55mV. This...
A heat engine is a system that converts heat or thermal energy and chemical energy into mechanical energy which in turn does mechanical work. It allows work to be done by using provided energy in the form of heat and then exhausts the heat that...
There is a basic difference in the character between the Indian Music and the Western Music. The Indian Music is basically an individualistic music in which a musician enjoys a great deal of freedom to express his own individual talents, which are improvisations. In Western...
Oil, coal, and natural gas are non-renewable energy sources known as fossil fuels which are currently the world’s primary source of energy. These are formed by prehistoric plants and animals that died over a million years ago and were gradually buried by layers of rock....
