What causes a solution to be conductive? When a solution conducts electricity, the charge is carried by ions moving through the solution. Ions are atoms or small groups of atoms that have an electrical charge. Some ions have a negative charge and some have a positive charge. Pure water contains very few ions, so it […]

What are the limitations of classical mechanics?
What are the limitations of classical mechanics? One experimental phenomenon that could not be adequately explained by classical physics was black-body radiation. Hot objects emit electromagnetic radiation. The burners on most electric stoves glow red at their highest setting. What are the inadequacy of classical mechanics? The inadequacy of Classical Mechanics are : It does […]
Is buoyant force always up?
Is buoyant force always up? The buoyancy force is caused by the pressure exerted by the fluid in which an object is immersed. The buoyancy force always points upwards because the pressure of a fluid increases with depth. What force is the opposite of buoyancy? Weight W acting vertically downwards works in the opposite direction […]

When a substance is boiling Will the added heat increase its temperature?
When a substance is boiling Will the added heat increase its temperature? Adding heat, however, does not always increase the temperature. For instance, when water is boiling, adding heat does not increase its temperature. This happens at the boiling temperature of every substance that can vaporize. What are the 4 conditions which allow bacteria to […]

Who is the father of model theory?
Who is the father of model theory? Tarski’s work included logical consequence, deductive systems, the algebra of logic, the theory of definability, and the semantic definition of truth, among other topics. His semantic methods culminated in the model theory he and a number of his Berkeley students developed in the 1950s and ’60s. What is […]
What are the 6 stages of the design process?
What are the 6 stages of the design process? Designers tend to use a six-stage process to organize their fact finding and decision making: (1) Empathy, (2) Define, (3) Ideate, (4) Prototype, (5) Test, and (6) Launch. Note, user refers to anyone who is a target of our design work. Empathy: Empathy is the foundation […]
