When two electrons have the same spin in the same orbital which principle is being violated? Pauli’s Exclusion Principle states that no two electrons in the same atom can have identical values for all four of their quantum numbers. In other words, (1) no more than two electrons can occupy the same orbital and (2) […]

What occurs after condensation? After Water Condenses Some of the water vapor in the atmosphere that condenses is stored in clouds. Clouds are more likely to form when the air is humid and contains more water vapor. The energy released when gaseous water vapor condenses to form liquid water droplets is called latent heat. What […]

How do I run for the first time? Choose a Training Plan Train three days a week. Run or run/walk 20 to 30 minutes, two days a week. Take a longer run or run/walk (40 minutes to an hour) on the weekend. Rest or cross-train on your off days. Run at a conversational pace. Consider […]

Does all life on Earth require sunshine? In different sense, every organism needs the heat provided by the sun because then the entire Earth would be too cold for any life to exist. So not every organism needs the energy of the sun for food, but all living things need the heat of the sun […]

Is H ion an acid or base? A solution with a high number of hydrogen ions is acidic and has a low pH value. A solution with a high number of hydroxide ions is basic and has a high pH value. The pH scale ranges from 0 to 14, with a pH of 7 being […]

How do you find the potential and kinetic energy of a pendulum? Energy in a Pendulum GPE can be calculated by multiplying the mass, the acceleration due to gravity, and the height change. Once the mass is let go, it starts to swing. Kinetic energy (KE) is the energy of motion, and is the product […]

Which is the least radiation phone? Smartphones like the Redmi Note 8 and Samsung Galaxy M31 have the lowest radiation levels of the lot, which means they are the safest to use. Meanwhile, Realme 6 Pro, Realme X3, and iPhone SE 2020 emit more radiation compared to the other models popular among 91mobiles readers. Which […]

What is the chemical formula of iron oxide? Fe2O3 Why is the reaction between Aluminium and iron III oxide a redox reaction? It is easy to see that the aluminium has been oxidised. This means that the iron oxide is the oxidising agent. This means that the aluminium is the reducing agent. What is thermite […]

What is the formula for volume in cylindrical coordinates? In cylindrical coordinates, we have dV=rdzdrd(theta), which is the volume of an infinitesimal sector between z and z+dz, r and r+dr, and theta and theta+d(theta). As shown in the picture, the sector is nearly cube-like in shape. How do you plot Cartesian coordinates? To plot any […]

What is the purpose of coiled wires? Coiled wires (also called retractile cords) are great for keeping long wires tidy and together. Their springy nature allows them to be stretched and then return to their coiled shape, keeping your wire localized and neat looking. Can Ethernet cable be coiled? A tightly coiled 10M length of […]
