What are the 3 types of aquifers? Confined aquifers have a layer of impenetrable rock or clay above them, while unconfined aquifers lie below a permeable layer of soil. Many different types of sediments and rocks can form aquifers, including gravel, sandstone, conglomerates, and fractured limestone. Does water harvesting increase ground water level? Rain water […]

What is the meaning of instant? noun. an infinitesimal or very short space of time; a moment: They arrived not an instant too soon. the point of time now present or present with reference to some action or event. a particular moment: at the instant of contact. What is an instant of time? An instant […]

What would happen if the moon cracked in half? The gravity from Luna would tug on the Earth; causing large tsunamis with the rise and fall of the tides more often than they currently occur, and an increase in earthquakes (look out California!), and an increase in volcanic activity, which would pump ash and carbon […]

Why does force equal mass times acceleration? Newton’s second law is often stated as F=ma, which means the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a). This means the more mass an object has, the more force you need to accelerate it. And the […]

Can I run a 220v dryer on 110V? It’s probably not possible to convert to 110V, although you’d have to find a user manual or contact the manufacturer to confirm. And even if you could, it would probably draw more power than a standard residential 110V outlet could supply. The only way to do this […]

How can the magnetic flux through a coil of wire be increased? There are three ways to change the magnetic flux through a loop: Change the magnetic field strength (increase, decrease) over the surface area. Change the area of the loop (increase by expanding the loop, decrease by shrinking the loop) Remember that flux is […]

What controls the jet stream? The earth’s rotation is responsible for the jet stream as well. The motion of the air is not directly north and south but is affected by the momentum the air has as it moves away from the equator. The reason has to do with momentum and how fast a location […]

Why am I gaining weight eating vegetables? How can that be? Vegetables are naturally low in calories and sodium. The report found that when many Americans eat vegetables they prepare them in ways that add calories and sodium while reducing fiber. So, if you eat more vegetables you will also get more fat, sodium, and […]

Why is atomic number more important? The number of protons in an atom is called its atomic number. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its […]

What is the current in the given circuit? Therefore, the value of the current is given as follows. ∴ The value of the current through the circuit is 0.1 A. So, the correct answer is “Option C”. What is the value of current I in the following circuit? According to Kirchhoff’s first law, total entering […]
