penetration testing methodology

The 's' electrons are more penetrating (maximum probability of finding near the nucleus) towards the nucleus than the p electrons. The order of penetration power in a given shell is s > p > d > f If the penetration power of the electron is more, it will be cl..

Scientific Methodology - Science is basically a collection of knowledge and information that is obtained by observation and testing of natural world, in a logical and orderly manner, and its interpretation. Hence, the basis of science is its orderly, step-wise procedure called s..

A manufacturing unit produces 2000 electric bulbs every month. Samples of the bulbs are to be tested for any manufacturing defects. What is the best sampling methodology for testing? => cluster sampling or random sampling or systematic sampling or full population..

a) Metal casting can be tested for cracks by putting them in baths of radioactive salts. The castings are then inspected for radioactivity to find out any penetration of salts into cracks. Absence of salt penetration indicates absence of cracks. b) Radioactive isotope..

Temperature is one of the essential and changeable environmental factors. It penetrates into every region of the biosphere and profoundly influences all forms of life by increasing or decreasing some of the vital activities of the organism. It is frequently a limiting factor for the..

Electric field can be quantitatively described by using the concept of electric flux. Electric flux is the number of electric field lines penetrating a surface or passing through a surface. The electric field can be uniform or non-uniform. Let us now try to find the electric flux passing ..

The epidermis usually forms projections known as epidermal hairs. In the root, the epidermal hairs are unicellular and are called as root hairs. The root hairs penetrate between the soil particles to absorb water. In the stem and the leaf, the epidermal hairs are multicellular and a..

Our body is made up of tissues, which are all composed of chemicals. We need an adequate supply of chemicals in the form of food, vitamins, hormones, and enzymes, which are in turn chemicals. For taking care of our health we need medicines. We find that chemicals and chemistry penetrate i..

The discovery of the phenomenon of radioactivity was purely accidental. In 1896, Henry Becquerel, a French scientist accidentally found that in presence of salt of uranium, photographic plates got heavily fogged even though they were wrapped in opaque paper. He concluded that the uranium salt..
