What is the thermal depolymerization technically?
The thermal Depolymerization Process (TDP): is a technical process that can convert any materials which consist of organic material (carbon chains or long chain polymers of hydrogen, oxygen and carbon), for example paper waste, wood, computer materials (plastic) and any human waste into short carbon chains with maximum length around 18 carbons (petroleum hydrocarbons).
Example of technology were related to physics?
Physics was instrumental in creating technology. Physics includes engineering and mechanics. Without these sciences much modern technology could not have been invented. In turn, new technology is used in physics to calculate exact measurements and simulate experiments.
How does forced convection differ from natural convection?
force convection is where the surface is forcefully heated up and the to is cooled down where when Nature happens, The photons come from the sun and bounce of the mlecules which creates heat and warms the air around it and that warm air heats up and goes up because it is less dense then the colder air. There it cools down and sinks because it is more dense than the air around it and it hits the ground only to be reheated and continues the cycle
How does energy get from a power plant to your home?
Energy gets from the power plant to customers via the power grid (high voltage power lines).
Transmission lines that generally operate at high voltages are responsible for long distance delivery of electricity. Substations step the voltage down to deliver it locally, and Transformers further step down the voltage to deliver it to the customer.
Note: There are no energy transformations invloved in this process. The power plant (whatever kind it might be) produces electricity (electromagnetic energy), and this is delivered to a user via the power grid. For energy transformation in power plants, refer to those specific questions.
Re-urbanisation is usually a government initiative to counter the problem of inner city decline.
Inner city decline is brought about when problems such as inadequate housing, transport problems, pollution and over-population occur in the city.
With these problems, the attractiveness of the city center is drastically reduced, resulting in loss of potential investment and an economically less productive city.
Reversal of urban decline, often through city center redevelopment acts as a catalyst to increase attractiveness of the city.
Thus encouraging people to move back to the city.
Describe what is the dual nature of technology?
Technology has both positive and negative affects (advantages and disadvantages (potential benefits and harms)) on society and environment including the possible improvement or declination of society and environment. This characteristic is sometimes called the dual nature of technology, a concept that applies not just to individual consumer durables such as a refrigerator or car, but to all levels from individual artifacts to industries and to the level of the global economy.

Group 1 on the periodic table shares which characteristics?
Group 1 on the periodic table, also known as the alkali metals, shares the characteristic of having 1 valence electron, which makes them very reactive. They are soft metals that react strongly with water to form alkaline solutions.
What is the function of the metal casing and tip of the bulb?
The metal casing of a light bulb serves as a protective barrier, preventing the bulb from breaking easily and protecting the delicate inner components from damage. The metal tip is where the electrical contact is made to supply power to the bulb, allowing the electricity to flow through the filament or LED inside the bulb, which then produces light.
What is the Difference between gravity wall and cantilever wall?
Gravity walls are supported by the earth itself in the downward direction. This generally applies to retaining walls. A Cantilever wall is not supported directly by the earth, but it is connected to another structure that is anchored. The cantilever wall, or any other structure containing the term cantilever, suggest that it "hangs out" of another anchoring structure without direct support from underneath.
What is the difference between a rollerball pen and a ballpoint pen?
Roller ball pens use a ball point like ballpoint pens, but use water-based or gelled ink, while ballpoint pens use oil-based inks.
In comparison to ballpoint pens, this gives roller ball pens advantages such as:
What is the strongest type of clear plastic as in sheets like lexan or plexi-glass.?
Lexan is the stronger of the two. Polycarbonate is the generic name and is 25 times stronger than acrylic or plexiglass. It is also stronger the PETG another type of clear plastic. It is also bulletproof and you can hammer a nail straight through without breaking the material. Here's some more info on this page about Polycarbonate and other plastics...
Your compass may not be working due to interference from nearby magnetic objects, a dead battery, or being too close to electronic devices. Make sure you are holding the compass level and away from metal objects when attempting to use it. If the issue persists, consider replacing the battery or seeking a new compass.
How long do you have to study to become a scientist?
Becoming a scientist usually requires obtaining a bachelor's degree in a science discipline, which typically takes four years. However, to pursue a career as a professional scientist, further education such as a master's or Ph.D. degree is often necessary, which can take an additional 2-8 years depending on the field of study and research involved.
How does insulation keep temperature inside?
The same way a cover or even clothes help you hold in heat.
Thermal insulation, which is in many homes and buildings, is believed by many to be the most common type of insulation. The design of thermal insulation is intended to decrease the transfer of heat between the interior of an edifice and the outside. Thermal insulation helps a building to maintain heat throughout the winter season. It also helps the building to remain cool during the summer months. Although, no material can completely hinder the transfer of heat from one area to another, there are; however, many resources that can slow down the transfer process.
The YO-505 is a deep-ocean research submarine that weighs approximately 24,000 pounds (10.8 metric tonnes). It is designed to withstand the high pressures of the deep ocean and carry a crew of up to five people on scientific missions.
Can I link one slide to another on flash 8?
Yes, you can link one slide to another in Flash 8 by using hyperlinks or buttons. You can create interactive elements on one slide that, when clicked, navigate to another slide within the presentation. This can be done by assigning actions or scripts to the interactive elements to control the navigation between slides.
If a person is tazed with 350000 volts will that person suffer internal burns?
It depends more on the amount of energy present, not the voltage. Scuffing your feet across a carpet and touching a metal doorknob produces thousands of volts, but it barely hurts you because there's only enough charge for an arc of very short duration.
kW (kilowatts) is a unit of power measurement, not temperature. It cannot be converted directly to Celsius. If you are referring to heat output or energy conversion, you would need additional information such as the efficiency of the system to calculate the temperature increase in Celsius.
What is the Use of ethyl cellulose in floating tablets?
Ethyl cellulose is commonly used in floating tablets as a hydrophobic polymer to provide controlled release of drugs by forming a barrier that slows down the penetration of water into the tablet core. This helps the tablet to float on the gastric fluids, prolonging the residence time in the stomach and improving drug absorption. Ethyl cellulose can also enhance the buoyancy of the tablet due to its low density, which aids in maintaining the tablet in the upper part of the stomach.
How long does a fiber optic light last for?
Light, fiber optic or otherwise does not disappear. It travels and keeps on traveling until something stops it. point a fiber optic into the sky and it goes until it is stopped by something. The question, "How long does fiber optic light last for" has only one answer, forever.
What are the Benefits and hazards of fast motion?
Benefits of fast motion include making scenes more dynamic, adding excitement, and creating a sense of urgency. However, hazards can include disorientation for viewers, loss of detail in the action, and potential for inducing motion sickness in some individuals.
State the basic principle of the pressure tube log?
The basic principle of the pressure tube log is to measure the pressure difference between two points along a tube to calculate fluid flow rate. By measuring the pressure at these points and knowing the fluid characteristics, the flow rate can be determined using a formula based on Bernoulli's principle.
What is the formation of a new species as a result of evolution?
The process of the formation of a new species is called speciation.
This usually requires some kind of event that splits a population into two or more isolated populations that can no longer interact. Ordinary evolutionary processes then act on each population independently, usually causing genetic divergencebetween the populations. If the divergence gets large enough that they either can no longer interbreed or refuse to interbreed between populations when again given the chance; then they are "new" species.
