Is electric force a field force? The electric field is defined mathematically as a vector field that associates to each point in space the (electrostatic or Coulomb) force per unit of charge exerted on an infinitesimal positive test charge at rest at that point…. Electric field Derivations from other quantities F / q How does […]

What happens if 2 Live wires touch?
What happens if 2 Live wires touch? Connecting two live wires in such a way to the switch will do nothing if both live wires are from the same source, as no current will flow as they should both possess the same potential measured in volts ( An electrical current flows between points of different […]
Why electric field is from positive to negative?
Why electric field is from positive to negative? The direction of the electric field is always directed in the direction that a positive test charge would be pushed or pulled if placed in the space surrounding the source charge. As such, the lines are directed away from positively charged source charges and toward negatively charged […]
What is a positive and negative relationship?
What is a positive and negative relationship? In a positive relationship, high values on one variable are associated with high values on the other and low values on one are associated with low values on the other. On the other hand a negative relationship implies that high values on one variable are associated with low […]
What happens if you fly after scuba diving?
What happens if you fly after scuba diving? Flying after diving increases your chance of developing Decompression Sickness (DCS). Dive professionals recommend waiting 12 hours after a single dive and 17 hours after repetitive dives. After multiple dive days or a decompression dive, you must wait 24 hours before flying (1). How many dives can […]
What is the equation for energy stored in a spring?
What is the equation for energy stored in a spring? The amount of elastic potential energy stored in a stretched spring can be calculated using the equation: elastic potential energy = 0.5 × spring constant × (extension) Ee = 1/2 k e. What is the equation for work done on a spring? Let the spring […]
What are the 2 magnetism of minerals?
What are the 2 magnetism of minerals? The most important magnetic carriers in rocks and soils are iron oxides, iron–titanium oxides, and iron oxyhydroxides. Magnetite (Fe3O4) and related ferrimagnetic minerals, such as titanomagnetite and maghemite (γ-Fe2O3), are the minerals, which have the largest saturation magnetization. What are the two ends of class? The two ends […]
Is Black Colour or shade?
Is Black Colour or shade? And many do consider black to be a colour, because you combine other pigments to create it on paper. But in a technical sense, black and white are not colours, they’re shades. How many types of black colors are there? +50 Shades of Black Color. What is the darkest shade […]
What adds more kinetic energy?
What adds more kinetic energy? In fact, kinetic energy is directly proportional to mass: if you double the mass, then you double the kinetic energy. Second, the faster something is moving, the greater the force it is capable of exerting and the greater energy it possesses. Thus a modest increase in speed can cause a […]
