What is a disadvantage of using solar energy? High initial costs for material and installation and long ROI (however, with the reduction in cost of solar over the last 10 years, solar is becoming more cost feasible every day) Needs lots of space as efficiency is not 100% yet. No solar power at night so […]

What happens when you reverse the current in a coil?
What happens when you reverse the current in a coil? When a coil drains a charged capacitor, the flow of charge in the coil does not stop, and the coil will “charge up” the capacitor again, but with reversed voltage. The voltage across the capacitor reverses, and the energy flow reverses, yet the direction of […]

Why is copper used instead of gold?
Why is copper used instead of gold? Gold, for example, is an excellent conductor of electricity, but it costs several times more than copper. If companies used gold to manufacture electrical wires, they’d essentially waste money, as copper is more conductive and costs less than its goal counterpart. What is the disadvantage of using aluminum […]
What are the two type of physical capital?
What are the two type of physical capital? There are two types of physical capital: fixed capital and working capital. Fixed capital includes those assets which can be used over many years in the process of production like machines in factory, building, tools etc. What are the classification of physical capital? Physical capital is divided […]
What are the best oxidizing agents?
What are the best oxidizing agents? The strongest oxidant in the table is F2, with a standard electrode potential of 2.87 V. This high value is consistent with the high electronegativity of fluorine and tells us that fluorine has a stronger tendency to accept electrons (it is a stronger oxidant) than any other element. Which […]
How a renewable resource can run out and give examples?
How a renewable resource can run out and give examples? Non-renewable resources are used faster than they can be replaced. Once they’re gone, they are, for all practical purposes, gone. Renewable resources are so abundant or are replaced so rapidly that, for all practical purposes, they can’t run out. Renewable resources include solar, wind, hydro, […]

What body type loses and gains weight easily?
What body type loses and gains weight easily? Everything you need to know about the mesomorph body type. Mesomorph refers to body types with a naturally high muscle-to-fat ratio. People with this body type typically respond well to weight training, finding it easier than other people to build and maintain muscle. They may also find […]
