How fast are laser beams in mph? Move your wrist very quickly, and the point of laser light may easily travel 50 feet in half a second — an equivalent speed of 68 mph (110 km/h). Can I bounce a laser off the moon? For the first time, scientists have successfully bounced a laser off […]
What is the process of an electromagnet?
What is the process of an electromagnet? An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the center of the coil. […]
Can the resultant of 3 vectors be zero?
Can the resultant of 3 vectors be zero? Answer. Three vectors are coplanar which means all three vectors are in the same plane. If direction of resultant of those two vectors is exactly opposite to the direction of the third vector. If all above conditions are satisfied, then the resultant of three vectors will be […]
What happens when the frequency of a wave decreases?
What happens when the frequency of a wave decreases? As the frequency decreases, the wavelength gets longer. There are two basic types of waves: mechanical and electromagnetic. What happens to the wavelength of a wave when you increase the amplitude? If the frequency increases, then the wavelength will be shorter, because there are more waves […]

Does reading increase IQ?
Does reading increase IQ? By adding to that storehouse, reading increases your crystallised intelligence. That explains why some IQ tests include vocabulary words, which generally serve as a reliable proxy of how clever you are. “Fluid intelligence” is that ability to solve problems, understand things and detect meaningful patterns. Is reading a sign of intelligence? […]
Does the bends go away?
Does the bends go away? While very minor symptoms of DCS may go away with just rest and over the counter pain medications, it is thought that treatment with recompression and oxygen is ideal to prevent any possible long term effects from the injury. What happens if you fly after diving? Flying after diving is […]
How do you know if alkene is symmetrical?
How do you know if alkene is symmetrical? A symmetrical alkene is an alkene in whose molecule the doubly bonded carbons bear the same ligands. eg. 1: In 1, each double bonded carbon bears two methyl groups. How do you identify asymmetric carbon? A carbon atom is asymmetric if it has four different chemical groups […]
What is the difference between indication and contraindication?
What is the difference between indication and contraindication? In medicine, a contraindication is a condition that serves as a reason to not take a certain medical treatment due to the harm that it would cause the patient. Contraindication is the opposite of indication, which is a reason to use a certain treatment. What are contraindications […]
What planets have humans landed on?
What planets have humans landed on? All three of those stages have been carried out for the Moon, Venus, Mars, Jupiter, Saturn, a comet, and several asteroids. Several Soviet and U.S. robotic spacecraft have landed on Venus and the Moon, and the United States has landed spacecraft on the surface of Mars. Does moon affect […]
