How many light years can we travel? Even if the fabric of space didn’t change over time, there are plenty of objects we can see today that could be farther away than 13.8 billion light-years. The only catch is that their light could travel for 13.8 billion light-years at most; how the objects move after […]

Who Solved the 2 body problem? The two-body problem consists of determining the motion of two gravitationally interacting bodies with given masses and initial velocities. The problem was first solved by Isaac Newton in 1687 using geometric arguments. How do you deal with two-body problems? How to Deal with the Two-body Problem Ask support from […]

Which sublevel is the lowest in energy? 1s Does the 3f sublevel exist? Does the 3f sublevel exist? (Note: the “3” stands for the 3rd energy level.) No, in the 3rd energy level there are only s, p, and d sublevels. The following sublevels exist in the 3rd energy level: 3s, 3p, and 3d. How […]

What fertilizer makes plants grow faster? High-nitrogen fertilizers are known for causing huge growth in plants, which is why many types are rich in nitrogen or include it as the main component. Fertilizers high in nitrogen will also restore bright green hues to your foliage. Which fertilizer works best? Best all-purpose fertilizers Jack’s Classic 20-20-20 […]

What is the volume of a mineral sample? Handle your samples to get an idea of how dense each one is, or how heavy each mineral feels for its size. The mass of each sample is measured using a balance or electronic scale. The volume of each sample can be measured (in milliliters) by the […]

Why do we not see the other side of the moon? We don’t see the far side because “the moon is tidally locked to the Earth,” said John Keller, deputy project scientist for NASA’s Lunar Reconnaissance Orbiter project. If the moon were a perfect sphere, then the gravity felt on the far side and the […]

Is salt the solvent in a saltwater solution? In a saltwater solution, salt is the solute and water is the solvent. What is the solvent in a salt water solution? In a NaCl solution (salt-water), the solvent is water. A solute is the component in a solution in the lesser amount. In a NaCl solution, […]

What is the relation between power and voltage? Electrical Energy in Circuits In other words, Energy = power x time and Power = voltage x current. Therefore electrical power is related to energy and the unit given for electrical energy is the watt-seconds or joules. Electrical power can also be defined as the rate of […]
