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 […]

Does higher voltage mean higher current? Hence, the specific answer to your question is no. High voltages do not equal high currents. Voltage and current move inversely to each other. Higher voltage means lower current, and vice-versa. How does voltage affect speed? Back to the original question: how does voltage affect speed? From the analysis […]

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 […]

Perihelion is the point of the Earth’s orbit that is nearest to the Sun. What is the significance of the Tropic of Cancer quizlet? What is the significance of the Tropic of […]

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 […]
