Why is the third class lever most common in the body? 3rd class levers are the most common levers, why? Although we use 3rd class levers more than any others in the human body, they in fact offer no mechanical advantage thus, regardless of where you apply the force, the force you apply must always […]
Why is energy of 1s electron lower than 2s electron?
Why they use 400 Hz instead of 50 and 60 hertz in the electric power system in an aircraft?
Why they use 400 Hz instead of 50 and 60 hertz in the electric power system in an aircraft? History of 400 Hz 400 Hz was first chosen for aircraft design as it ensured a more compact design (and hence lighter weight) for the electrical systems. Generators providing 400 Hz power use less copper in […]
Are human beings natural resources?
Are human beings natural resources? All human beings are animals and therefore depend on the material, natural resources which constitute their environment. Human beings should not try to conquer their environment but learn to live in harmony with it. Are people considered man-made? Are humans natural things or man-made things? So according to the definition […]
Is radioactive dating absolute or relative?
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 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 […]
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. […]
