What are the two basic types of speedometer?
What are the two basic types of speedometer? There are two types of speedometers: electronic and mechanical. Because the electronic speedometer is actually a relatively new invention — the first all-electronic speedometer didn’t appear until 1993 — this article will focus primarily on the mechanical speedometer, or the eddy-current speedometer. What do numbers symbolize on […]
Does acceleration due to gravity depend on mass?
Does acceleration due to gravity depend on mass? The acceleration due to gravity does not depend on the mass of the object falling, but the force it feels, and thus the object’s weight, does. Why does mass resist acceleration? The more mass an object has the more weight it will have. Weight is caused by […]
Can we charge an insulator?
Can we charge an insulator? Charge cannot flow along or through an insulator, so its electric forces remain for long periods of time. (Charge will dissipate from an insulator, given enough time.) Do conductors attract insulators? If the insulator started with positive charge on it, that means electrons are missing inside of it. The electrons […]
In what direction is the net force exerted on the moon?
In what direction is the net force exerted on the moon? We know from Newton’s second law of motion that an object experiencing a net force undergoes acceleration. In the case of the moon orbiting the Earth (or any object orbiting another object to which it is attracted by some force), the net force on […]
What type of research is a descriptive study?
What type of research is a descriptive study? Descriptive research is a type of research that describes a population, situation, or phenomenon that is being studied. It focuses on answering the how, what, when, and where questions If a research problem, rather than the why. What type of descriptive research study measures a population at […]
Does anything have 100 efficiency?
Does anything have 100 efficiency? A system can never be 100% efficient. The reason behind this is because of heat and sound energy are lost in some amount in every system. No matter they are waste or not. So a system doesn’t exist, with 100% efficiency. Is human body energy efficient? Alas, our bodies are […]
Que se conserva en el choque elastico?
¿Que se conserva en el choque elastico? En física se dice que el choque entre dos o más cuerpos es elástico cuando se conserva la energía cinética total del sistema de cuerpos durante la interacción. ¿Qué efecto produce la energía cinetica en un choque? Colisiones. Si el choque es perfectamente inelástico (plástico) la energía cinética […]
How are potential and distance related?
How are potential and distance related? Moving towards and away from the charge results in change of potential; the relationship between distance and potential is inverse. For one point charge, potential will be constant for all points a certain radial distance away. Multiple points of the same potential are known as equipotential. How do you […]
