Why does path of light beam become visible while passing through a smoked room? Smoke is made up of tiny particles. The particles reflect light rays to all directions, including where we stand. As a result, we can see the path of the beam on the side. What is the example of Tyndall effect? When […]
Can we split a quark?
Can we split a quark? Quarks,and leptons are thought to be elementary particles, that is they have no substructure. So you cannot split them. Quarks are fundamental particles and cannot be split. Can you split a Preon? The smallest you could break an atom down would be to hydrogen, with one proton, one neutron and […]

Why do humans hear better in air than underwater?
Why do humans hear better in air than underwater? On land, sound travels through air conduction. This means that sound waves travel through the air, causing your eardrum to vibrate. Researchers have determined that bone conduction allows us to hear sounds underwater that are much higher in pitch than sounds we hear on land. Can […]
Can two electric field lines intersect each other?
Can two electric field lines intersect each other? Electric lines of force never intersect because, at the point of intersection, two tangents can be drawn to the two lines of force. This means two directions of the electric field at the point of intersection, which is not possible. Why can’t two field lines intersect each […]

What are 4 factors that affect weather?
What are 4 factors that affect weather? Although many factors combine to influence weather, the four main ones are solar radiation, the amount of which changes with Earth’s tilt, orbital distance from the sun and latitude, temperature, air pressure and the abundance of water. What region of Earth has the least insolation? The sun’s rays […]
What is dynamic warm up and why use it?
What is dynamic warm up and why use it? In simple terms, a dynamic warm-up is “moving while you stretch” or stretching through a joint’s full range of motion and preparing muscles for more intense exercise to come. A dynamic warm-up promotes blood flow, helps PREVENT INJURY and muscle soreness, as well as helps improve […]
