How do you solve impedance? In AC circuits, Ohm’s Law takes the more general form: E = I⋅Z, where E is voltage and I is current, as before. The new term, Z, is impedance, a vector combination of: Resistance, R (in ohms), with voltage drops in phase with the current. What is the impedance of […]

What are possible causes for a magnetic field? If you have a rotating electric current, it will create a magnetic field. On Earth, flowing of liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends […]

Which describes how the spring constant affects the potential energy? Which describes how the spring constant affects the potential energy of an object for a given displacement from an equilibrium position? The higher the spring constant, the greater the gravitational potential energy. The higher the spring constant, the greater the elastic potential energy. How does […]

Is metallic physical or chemical property? Physical Properties of Metals State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days). Luster: Metals have the quality of reflecting light from their surface and can be polished e.g., gold, silver and copper. Is […]

Is the human body a heat engine? The body is a heat engine. It converts chemical energy of the food consumed into both heat to sustain metabolism and work. The harder the body exercises or works, the greater the need to reject heat in order for the body to maintain thermal balance. Is a car […]

At what age do you start wearing glasses? That may be as young as a few months of age. Healthcare providers who specialize in children’s eye care say kids usually become nearsighted or farsighted between ages 6 and 12. Farsightedness may be diagnosed even earlier, sometimes in infancy. Even infants can wear glasses if they […]

What is the most common form of physical evidence? Physical evidence refers to any item that comes from a nonliving origin, while biological evidence always originates from a living being. The most important kinds of physical evidence are fingerprints, tire marks, footprints, fibers , paint, and building materials . Biological evidence includes bloodstains and DNA […]
