What will adding an iron core to the inside of the electromagnet do to the magnet? An iron core makes a temporary electromagnet. It loses its magnetism as soon as the switch is opened and the current is switched off. A steel core makes a more permanent magnet. It does not lose its magnetism quickly […]

What is aerobic pond? A lagoon that forms the third treatment stage in waste stabilization ponds (WSP). It is a shallow pond with large surface area to enable light penetration and oxygenation by wind mixing. The effluent is generally free of pathogens but rich in nutrients and can be reused for fertigation or aquaculture. What […]

What are hydraulic shears used for? Hydraulic shears are used in high volume metal fabricating operations that require the ability to accurately and quickly cut and score sheets of metal. Hydraulic shears, contrary to their name, look nothing at all like shears. How does a hydraulic shear work? With shear machining, the tool’s cutting edge […]

What is the impact of externalities? Technical externalities have an impact on the consumption and production opportunities of unrelated third parties, but the price of consumption does not include the externalities. This exclusion creates a gap between the gain or loss of private individuals and the aggregate gain or loss of society as a whole. […]

How do you find a and b/in van der Waals equation? Find out the unit and dimensions of the constants aandb in the van der Waal’s equation (P+aV2)(V-b)=Rt, where P is pressure , v is volume , R is gas constant , and T is temperature. Solution : We can add and subtract only like […]

How fast are STEM jobs growing compared to non STEM jobs? STEM occupations are projected to grow by 17.0 percent from 2008 to 2018, compared to 9.8 percent growth for non-STEM occupa- tions. STEM workers command higher wages, earning 26 percent more than their non- STEM counterparts. How much does the average stem job pay […]

What is the function of the hot end in a 3D printer? The Hotend is the element of the 3D printer which function is to melt the filament. The filament is introduced in solid state into one end and it is extruded by the opposite end in a controlled manner. How hot should my 3D […]

Under what situation maximum power transfer theorem is not applicable? Maximum Power Doesn’t Mean Maximum Efficiency The Maximum Power Transfer Theorem does not: Maximum power transfer does not coincide with maximum efficiency. Application of The Maximum Power Transfer theorem to AC power distribution will not result in maximum or even high efficiency. Where is maximum […]
