Does moving a charge along an equipotential surface do any work? The work done by the electric field on a particle when it is moved from one point on an equipotential surface to another point on the same equipotential surface is always zero. Why is there is no work done in moving a charge from […]
What does the strength of gravity between two objects depend on?
What does the strength of gravity between two objects depend on? The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects. Which of the following […]
Where is the net electric field zero?
Where is the net electric field zero? In Region II, between the charges, both vectors point in the same direction so there is no possibility of cancelling out. In Region III, the fields again point in opposite directions and there is a point where their magnitudes are the same. It is at this point where […]
Which is the halogen that is in period 5?
Which is the halogen that is in period 5? fluorine Is Iodine a period 5 halogen? The halogens are located on the left of the noble gases on the periodic table. These five toxic, non-metallic elements make up Group 17 of the periodic table and consist of: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), […]
What happens if one bulb goes out in a series circuit?
What will happen when oceanic crust converges with each other?
What will happen when oceanic crust converges with each other? If the two plates that meet at a convergent plate boundary both are of oceanic crust, the older, denser plate will subduct beneath the less dense plate. The older plate subducts into a trench, resulting in earthquakes. Melting of mantle material creates volcanoes at the […]
Why is night so quiet?
What is the difference between UV light and blacklight?
What is the difference between UV light and blacklight? Black light is nothing but UVA light, while UV light is basically composed out of UVA, UVB and UVC. So in other words, black light is UV light(450-100nm), covering the 400-320nm spectrum. What color is urine under black light? yellow What color does dog urine glow […]
Which disease is most infectious?
Which disease is most infectious? History’s nine most contagious diseases: Where are they now? Smallpox. Emerging in human populations around 10,000 B.C., smallpox eventually killed between 300 and 500 million people worldwide, during the 20th century alone. Rabies. Tuberculosis. Leprosy. Typhoid Fever. Bubonic and Pneumonic Plagues. Malaria. HIV/AIDS. What are the top 5 common viral […]
Can you make the coil spin in both directions with your current setup?
Can you make the coil spin in both directions with your current setup? Simply put, DC motors can turn in either direction (clockwise or counter-clockwise) and can be easily controlled by inverting the polarity of the applied voltage. Strictly speaking, the motors can actually create a force in either direction. What causes the coil to […]
