internal and external force

This is the simplest type of modem to install because you don't have to open the computer. External modems have their own power supply and connect with a cable to a computer's serial port. The telephone line plugs into a socket on the rear panel of the modem. Because external m..

Most internal modems come installed in the computer you buy. Internal modems are more directly integrated into the computer system and, therefore, do not need any special attention. Internal modems are activated when you run a communication programme and are turned of..

Factors Affecting Photosynthesis - External Factors - Photosynthesis is influenced by two categories of factors - external or environmental and internal or plant factors. According to the law of limiting factors, put forward by F.F.Blackman in 1905, photosynthesis is l..

Respiratory system - Lungs are the respiratory organs. The passage way for air is formed by external nostrils, pharynx, larynx, trachea and bronchi. Lungs contain large number of minute alveoli in which external respiration takes place. Surrounding the lungs and the heart is a t..

The earth summit held in 1992 at Rio de Janeiro resulted in a convention on biodiversity, which came into force on 29 t h December 1993. The key objectives of the conservation are: i) Conservation of biological diversity ii) Sustainable use of biodiversity iii) Fair and equitable sharing ..

Photosynthesis is influenced by two categories of factors - external or environmental and internal or plant factors. According to the law of limiting factors, put forward by F.F.Blackman in 1905, photosynthesis is limited by the most limiting facto..

According to Newton's first law of motion every body continues to be in its state of rest or uniform motion along a straight line unless an external force acts on it. This means that a ball moving on a horizontal surface should continue to move indefinitely as no force..

A vegetable vendor applies force to push the cart, a driver applies force either to stop the car or to change the speed or direction of motion and a football player kicks the ball to set it in motion. In all the above examples, the force applied on a body can bring abo..

External forces acting on a body, bring about a change in its state or configuration. The latter is possible when the body is not free to move, but the molecules are compelled to change their positions. Such forces are called deforming forces..

In the previous chapters we studied the motion of a body moving with uniform speed in a straight line and also learnt to calculate the distance traveled by a body in any given time. We then observed that the bodies do not always move with uniform speed and an external unbalanced forc..
