How much oil is saved by recycling plastic? Plastic. One ton of recycled plastic saves 5,774 Kwh of energy, 16.3 barrels of oil, 98 million BTU’s of energy, and 30 cubic yards of landfill space. Can you make plastic without oil? Originally Answered: Can plastics be created without oil? Yes, but only with difficulty. The […]

When an inductor is connected to a 200v? Solution. When the inductor is connected across the 200 V DC circuit 1 A current flows because in this case the inductor simply acts as a resistor and there is no inductive reactance. When an inductor is connected to a 230V DC source? When an inductor is […]

What chemicals are mixed when making fire? When potassium chlorate and ordinary table sugar are combined, and a drop of sulfuric acid is added as a catalyst, the two react violently with each other, releasing large quantities of heat energy, a spectacular purplish flame, and a great deal of smoke. Can you describe the solutions […]

What does 60 75 mean on a circuit breaker? 60/75°C Wire — All circuit breakers rated 125 A or less are marked for use with 60° C, 60/75°C or 75°C only wire. This marking indicates the proper wire size for termination in accordance with Table 310.15(B)(16) of the NEC . Are breakers rated for 90 […]

Is angular momentum axial or polar vector? Likewise, the momentum vector is the velocity vector (a polar vector) times mass (a scalar), so is a polar vector. Angular momentum is the cross product of a displacement (a polar vector) and momentum (a polar vector), and is therefore a pseudovector. What is the meaning of axial […]

What is a non example of a molecule? What Is Not a Molecule? Single atoms of elements are not molecules. A single oxygen, O, is not a molecule. When oxygen bonds to itself (e.g., O2, O3) or to another element (e.g., carbon dioxide or CO2), molecules are formed. What is a non example of a […]

What is an acoustician? The Job and What’s Involved. Acoustics is the name given to the branch of science that deals with the study of sound. Acousticians help to manage, regulate and control noise and vibration in the home, in workplaces and the environment. What are the types of sound? There are two types of […]

Is Ferrel cell high or low pressure? At the equator there is an area of low pressure, due to the rising and expanding air. At around 30º North the sinking air creates an area of high pressure. This cell is thermally direct. The Ferrel cell is found between the Hadley and Polar cells and lies […]

What are the three conditions of equilibrium? A solid body submitted to three forces whose lines of action are not parallel is in equilibrium if the three following conditions apply : The lines of action are coplanar (in the same plane) The lines of action are convergent (they cross at the same point) The vector […]

How do I get arcseconds? Because 2π times the radius equals the circumference, circle angles can be measured in radians, with 2π of these making up one full revolution. Or similarly, 0.017453 radians per degree. To convert from radians to arcseconds, multiply by 206,265 arcseconds per radian. What is 1 arc second in meters? Arc […]
