Description : Ball pen functions on the principle of : (1) Viscosity (2) Boyle's Law (3) Gravitational force (4) Surface tension
Last Answer : (4) Surface tension Explanation: The ballpoint pen is one of the most simple and yet ubiquitous devices whose function depends on surface tension. With a pen held upright, gravity and surface tension act in concert to get ink onto the ball.

Description : How bad is it to smoke weed out of an aluminum can or a metal ball point pen as opposed to the typical glass piece?
Last Answer : It’s bad for your brain to smoke pot in general, regardless of what you are using. And no, if you’re worried about weird fumes or it mixing with the pot and causing bad effects, no…it’s just as bad as using glass or an apple and shouldn’t be any worse or better.

Description : A fountain pen works on the principle of (1) Flow of liquids from higher to lower potential (2) Capillary action (3) Bernoulli's principle (4) Viscosity of liquids
Last Answer : (2) Capillary action Explanation: A fountain pen is a nib pen that, unlike its predecessor the dip pen, contains an internal reservoir of water-based liquid ink. The pen draws ink from the ... to flow in narrow spaces without the assistance of, and in opposition to external forces like gravity.

Description : That an Iron ship floats in water but an Iron ball sinks, is an example of - (1) Newton's second law (2) Pascal's law (3) Archimedes Principle (4) Dalton's law
Last Answer : (3) Archimedes Principle Explanation: The floating of an iron ship in water is an example of Archimedes principle. Archimedes' principle states that an object floats on water if the weight of the water ... . Since the average density of the ship as a whole is less than the density of water.
