How do you find a variable in an equation? If the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from […]
Why do electrons lose energy?
Why do electrons lose energy? An excited atom is unstable and tends to rearrange itself to return to its lowest energy state. When this happens, the electrons lose some or all of the excess energy by emitting light. Does losing an electron release energy? When electrons are removed from an atom, that process requires energy […]
Can you use a solenoid as a relay?
Can you use a solenoid as a relay? Solenoids are a type of relay engineered to remotely switch a heavier current (typically ranging from 85-200 amps). In contrast to the smaller electromechanical cube relays, a coil is used to generate a magnetic field when electricity is passed through it, which effectively opens or closes the […]
What does medium rare steak feel like?
What does medium rare steak feel like? If you’d like your steak medium-rare, it should feel like your cheek: tender and soft but still fleshy (as opposed to raw, which would be just soft). If you want a medium steak, touch your chin: The steak should still be tender, but with some resistance. How do […]

What is capacitance and dielectrics?
What is capacitance and dielectrics? capacitance: amount of charge stored per unit volt. dielectric: an insulating material. dielectric strength: the maximum electric field above which an insulating material begins to break down and conduct. What is resistance and capacitance? Resistance is the measure of the amount of energy dissipated by the resistor. While capacitance is […]
What is kVp vs mAs?
What is kVp vs mAs? * kVp: the power and strength of the x-ray beam (quality of the x-rays). * mAs: the number of x-ray photons produced by the x-ray tube at the setting selected (quantity of x-rays). * time: how long the exposure lasts. Understanding Technique. kVp stands for kilovoltage peak. What is source […]
Which statement is part of the Malthusian theory quizlet?
Which statement is part of the Malthusian theory quizlet? Malthus argues that population increases exponentially example if a couple have two children and each of those two children have two children the result would be four grandchildren if those four grandchildren each have two children the result to be eight Great grandchildren if a couple […]

Can current flow through an insulator?
Can current flow through an insulator? In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. Why does current flow in a conductor? When an […]
