What is the major difference between descriptive and experimental research? Descriptive research refers to research which describes a phenomenon or else a group under study. Experimental research refers to research where the researcher manipulates the variable to come to an conclusion or finding. What is an example of a descriptive experiment? To experiment is defined […]
What role does groundwater play in the formation of caves?
What role does groundwater play in the formation of caves? Caves are one of the types of landforms created by groundwater erosion. Working slowly over many years, groundwater travels along small cracks. The water dissolves and carries away the solid rock. This gradually enlarges the cracks. Is responsible for the formation of subterranean caves? Solution […]
Do neutron bombs exist?
Do neutron bombs exist? A neutron bomb is actually a small thermonuclear bomb in which a few kilograms of plutonium or uranium, ignited by a conventional explosive, would serve as a fission “trigger” to ignite a fusion explosion in a capsule containing several grams of deuterium-tritium. Does Russia have a neutron bomb? Hence, Moscow has […]
Is ruby laser pulsed or continuous?
Is ruby laser pulsed or continuous? Although it lases at the standard deep-red 694.3 nm wavelength, it is both diode-pumped (making it very stable and efficient) and continuous-wave (opening up many uses not available to pulsed ruby lasers). What is pulsed mode? (C) The resulting voltage pulse that is developed across the circuit of (A) […]
What are examples of perfectly inelastic collisions?
What are examples of perfectly inelastic collisions? Another common example of a perfectly inelastic collision is known as the “ballistic pendulum,” where you suspend an object such as a wooden block from a rope to be a target. What makes a collision perfectly inelastic? An inelastic collision is a collision in which there is a […]

Will your brain let you stub your toe?
Will your brain let you stub your toe? It’s scientifically proven that your brain won’t let you stub your own toe. Can stubbing your toe break it? Stubbing a toe can even cause breaks, sprains, broken nails, and infections. The pain of a stubbed toe usually subsides after a few minutes. In some cases, however, […]
What is a saturated solution give example?
What is a saturated solution give example? Carbonated water is saturated with carbon, hence it gives off carbon through bubbles. Adding sugar to water until it no longer dissolves creates a saturated solution. Continuing to dissolve salt in water until it will no longer dissolve creates a saturated solution. The Earth’s soil is saturated with […]
Do magnets ruin dvds?
Do magnets ruin dvds? no normal magnet can damage a CD/DVD. The CD/DVD is physically burned into the surface of the disc in a non-magnet way. However CD/DVD still contain metal so if you had a ridiculously strong magnet there is a minute chance of damaging it. Do magnets destroy CDs? Though they might not […]
