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, […]

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 is the significance of aphelion and perihelion? Aphelion is the point of the Earth’s orbit that is farthest away from the Sun. 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 […]

What information does the API symbol? API Service Symbol ”Donut” The API “Donut” identifies oils that meet current API engine oil standards. It includes the SAE viscosity grade of the oil, API standards met by the oil, and other important performance parameters. Can I mix synthetic and regular oil? yes. If you don’t have a […]

What is the meaning of frequency and examples? Frequency describes the number of waves that pass a fixed place in a given amount of time. So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. For example, an “A” note on a violin string […]

Why different objects kept on a table at room temperature do not exchange heat with table? Answer. Answer: The sense of touch allows us to recognise temperature differences of objects in the same room which we could easily assume should all be at that same room temperature. The temperature of an object is dependant on […]

Which type of collision is most often seen in football? Perfectly inelastic collisions can be analyzed in terms of momentum. When two objects, such as the two football players, collide and move together as one mass, the collision is called a perfectly inelastic collision. What happens when two tennis balls collide? At impact, the cue […]
