What is real and apparent Expansivity? The real (or absolute) expansivity of a liquid is the fraction of its volume by which it expands per kelvin rise in temperature. The apparent expansivity of a liquid is the fraction of its volume by which the liquid appears to expand per kelvin rise in temperature when heated […]

What is the pathway of sound vibrations to the inner ear?
What is the pathway of sound vibrations to the inner ear? The vibrations are transmitted further into the ear via three bones (ossicles): malleus (hammer), incus (anvil), and the stapes (stirrup). These three bones form a bridge from the tympanic membrane to the oval window. 5. Once sound passes through the oval window, it enters […]
When a positive charge moves in the direction of the electric field what happens?
When a positive charge moves in the direction of the electric field what happens?
