Does light travel faster in air or water? Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water. What happens when two light waves collide? Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium. […]
What are the vertical and horizontal components of a projectile?
What are the vertical and horizontal components of a projectile? The trajectory of a projectile depends on motion in two dimensions. The x component is the horizontal motion of the projectile, and the y component is the vertical motion of the projectile. Once a projectile is in motion, it is in freefall. The only acceleration […]
What is Reynolds number value?
What is Reynolds number value? Reynolds number is a dimensionless quantity that is used to determine the type of flow pattern as laminar or turbulent while flowing through a pipe. Reynolds number is defined by the ratio of inertial forces to that of viscous forces. Is high Reynolds number viscous? The viscous regions in high […]
What type of reaction is this 4 NA O2 → 2 Na2O?
What type of reaction is this 4 NA O2 → 2 Na2O? synthesis reaction Is Na O2 a redox reaction? Oxidation and reduction occur simultaneously; when one species is oxidized, the other is reduced. Hence we call these redox reactions. In reaction (a), Na is oxidized by losing electrons and O is reduced by gaining […]
What compares Probeware to traditional analog tools?
What compares Probeware to traditional analog tools? Measurements by traditional analog tools are good to a larger number of significant figures. Measurements by traditional analog tools are less prone to experimental error. Probeware is typically very difficult to transport. Probeware is useful for obtaining many measurements in rapid succession. Which tool is used to measure […]
What are the dominant features of industrial society?
What are the dominant features of industrial society? As the basic form of modern society, the term ‘industrial society’ covers both CAPITALIST SOCIETIES, since both exhibit the following common features: factory-based production, a declining proportion of the population employed in agriculture, the separation of the household from production, increases in the level of … What […]
Who is father of immunology?
Who is father of immunology? Louis Pasteur What did Louis Pasteur conclude was causing diseases? After accidentally exposing chickens to the attenuated form of a culture, he demonstrated that they became resistant to the actual virus. Pasteur went on to extend his germ theory to develop causes and vaccinations for diseases such as anthrax, cholera, […]

According to this method, to increase the chance of having a girl, you should have intercourse about […]
Can pure breeding be heterozygous?
Can pure breeding be heterozygous? A cross between two different true-breeding individuals will produce heterozygous offspring. True-breeding individuals are homozygous, with two of the same allele for a gene, whereas heterozygous individuals have two different alleles for a gene. What happens when both parents are heterozygous? If both parents are heterozygous (Ww), there is a […]
How does the split ring commutator change the direction of the current?
How does the split ring commutator change the direction of the current? The split ring commutator reverse the current in the armature every half revolution when the commutator changes contact from one brush to another. This reverse in current causes the forces acting on the coil to be reversed. This helps the coil continue to […]
