air conduction greater than bone conduction

. This process is called ionisation . Electrolyte conductivity is smaller than that of metals by a factor of 10 - 5 to 10 - 6 at room temperature. This is due to the smaller number density of ions as compared to free electrons, greater viscosity of the medium in which they move ..

An organization conducted a test for a group of students, whose scores are normally distributed with mean 70 and standard deviation 3. Find the probability that the score of a particular student is greater than 67. => 0.8413 or 0.1587 or 0.3413 or 0.5000..

. As a result, the quantity of carbon dioxide reduces and that of oxygen increases. Since plants use carbon dioxide and animals oxygen, the percentage of these gases in air remains fairly constant. Remember : It is interesting to note that more photosynthesis takes place in the sea than o..

. Let us now list out the applications of sound waves: (1) Submarines can be detected by the under-water sound waves produced by the propellers. (2) Some bones conduct sound and this type of bones are used to design hearing ai..

A material medium is necessary for sound propagation - Ordinarily, we hear sound, transmitted through the air. Unlike light, sound cannot pass through vacuum. This was discovered in 1654 by Otto Von Guericke. Let an electric bell be enclosed within a bell jar which is placed over a disc. ..

Minerals are inorganic nutrients. They include both metallic and non-metallic elements, which are taken by the body in the form of salts. There are 24 elements that are used in our body. They have various functions such as formation of tissues such as the bone, conduction ..

The nasal passage is lined by the nasal mucosa that have hairs and mucou-secreting cells. The hairs act like filters to remove the dust particles from the inhaled air. The mucous secreted by Bowman's gland keeps the inhaled air moist. The chemicals released by the various odorif..

Thermo-couples can be used to generate electric power using Seebeck effect, in remote areas. This can be done by heating one junction of a thermo-couple in a flame (e.g., of kerosene lamp) and keeping the other junction in air at room temperature. The thermo-emf so generated can be used t..

It is a collection of nervous tissue running along the back bone. It is, in fact, protected by the vertebral column. It is a continuation of the brain. It consists of a central canal that has cerebrospinal fluid that is continuous with the fluid in the brain. The canal is surrounded ..
