The limbs in human beings are designed on the same basic plan, as that of the pentadactyl limb, because each limb ends in five digits. The limb bones support the arms (upper limbs) and legs (lower limbs). The bones of the legs are stronger than those of the arm..

A microscope is an optical device which produces a highly magnified image of very small object such as micro-organisms. Based on the design, there are two types of microscopes. They are, simple microscope and compound microscope..

A microphone is a device that transforms sound pressure into electrical energy. In most types of microphone, the sound pressure acts upon a thin plate or diaphragm, setting it into vibration, and this mechanical motion is then utilised to produce electrical effects. The chief types are described b..

Module Two: Sampling and Experimentation - Overview of methods of data collection: Census Sample survey Experiment Observational study Planning and conducting surveys: Characteristics of a well-designed and well-conducted survey Populations, samples, and random selection Sources of bias i..

Parameters that Define the Orbit of a Satellite - Expertise is required in the planning, designing and fabrication of satellites. Each satellite has to be designed according to the purpose for which it is used. Also, one should have the basic infrastructure to fabricate the part..

The process of electrolysis is exactly opposite to one that takes place in a voltaic cell. A voltaic cell or a battery uses its chemical energy to produce electrical energy. While in electrolysis, electrical energy is used to bring about a chemical change. Humphrey Davy (1807) showed this in his ex..

They are made in various designs to reduce friction. They reduce friction because rolling friction is smaller than sliding friction. These bearings are also lubricated to further improve their function. ..

A plane mirror is used: as a looking glass to view ourselves by interior designers to create an illusion of depth to fold light as in a periscope and other optical instruments to make kaleidoscope, an interesting t..
