Is radioactive dating absolute or relative? Radiometric dating Most absolute dates for rocks are obtained with radiometric methods. These use radioactive minerals in rocks as geological clocks. The atoms of some chemical elements have different forms, called isotopes. These break down over time in a process scientists call radioactive decay. Is absolute dating quantitative? Absolute […]
How many additional electrons does this atom of oxygen?
How many additional electrons does this atom of oxygen? two additional electrons What 4 elements must follow the octet rule? The rule is applicable to the main- group elements, especially carbon, nitrogen, oxygen, and the halogens, but also to metals such as sodium and magnesium. Valence electrons can be counted using a Lewis electron dot […]
Why is energy of 1s electron lower than 2s electron?
What is the difference between physical and logical storage?
What is the difference between physical and logical storage? Physical (disk) storage contains all the files in the database. Logical storage structures, such as tablespaces, segments, extents, and blocks, appear on the disk but are not part of the dataset. A book serves as a helpful analogy for the difference between physical and logical storage. […]

How do you read a vernier scale angle?
How do you read a vernier scale angle? Take a reading from the main scale: read the number opposite the marking “0” on the vernier scale. Make sure you choose the half-degree which is SMALLER than the “0” on the vernier scale. This yields the angle to the nearest half-degree. How do vernier scales work? […]
What is a radical equation?
What is a radical equation? A radical equation is one where the variable appears under a square root sign. (For the time being we only worry about square roots, not cube roots or other interesting things.) The general technique for solving a radical equation is: isolate the square root sign (and whatever’s under it) on […]
What is the two components of a solution?
What is the two components of a solution? Components of a Solution It has basically has two components i.e. a solvent and a solute. Solvent: The component of a solution which dissolves the other component in itself is called solvent. A solvent constitutes the larger component of the solution. For example, a solution of sugar […]
Which of the following does not play a role in convection in the mantle?
Which of the following does not play a role in convection in the mantle? The core does not play an active role in mantle convection. The magnitude of the bottom TBL depends on the cooling rate of the mantle, the pressure and temperature dependence of the physical properties and the radioactivity of the deep mantle. […]
