What causes earthquakes? You might think Earth is a giant, solid lump of rock, but you'd be wrong. In some ways, it's like a hard-boiled egg: at the center, there's thecore(part solid, part runny liquid), seething away inside a thick, more-or-less solid layer called themantle, ...
What are contact forces? Give examples. What work was done by the electric force? How to find force? What is the force that opposes motion called? What is the force in the force table? What kind of forces do you use on the force table? What is a friction force? What is the frictio...
Electric force is a force present between a pair of bodies that have positive or negative charge. When the charge on both the bodies are same, the electric force felt by the two bodies is call repulsive electric force. Attractive electric force is only felt by the bodies when they both do...
An electric charge, which can be either positive or negative, is a property of matter that causes two objects to attract or repel. If the objects are oppositely charged (positive-negative), they will attract; if they are similarly charged (positive-positive or negative-negative), they will re...
But for Cepheids, there is an additional mechanism called the kappa mechanism: the increased temperature caused by contraction increases ionization of helium, which drains energy from the star and accelerates the contraction; conversely, the cooling caused by expansion causes the ionized helium to ...
An electric fire is a prime example showing how a current causes heat to be generated. The actual amount of heat is governed not only be the current, but also be the voltage and the resistance of the conductor. Magnetic effect: Another effect which can be noticed is that a magnetic field...
A Type Ia supernova occurs when a white dwarf in a binary system draws more and more mass from its companion star, until it reaches the Chandrasekhar limit, at which point its gravitational forces are strong enough to cause a collapse that increases the pressure to the point where a super...
Commercial fleets could go electric rapidly. Understanding total cost of ownership and focusing on specific cases is critical. (PDF-639 KB) There’s nothing new about electric trucks; they have labored on the streets of major cities across the world since the first decades...

Market failure refers to a situation defined by an inefficient distribution of goods and services in the free market. In an ideally functioning market, the forces ofsupply and demandbalance each other out, with a change on one side of the equation leading to a change in price that maintains ...
