When we place one end of an iron rod in a fire, the other end also heats up after a while. We say heat has been conducted along the rod from the hot end. Conduction is the process by which heat is transmitted through a medium from one particle to another. The heat is transmitted from the hot to the cold end.
Most metals are good thermal conductors. A metal surface feels colder than a cement surface although they are both at the same temperature. This is because e

Physics 2010 – Online
30 April 2014
Physics is a controlling factor in our vast universe. It literally controls how our reality operates and how our existence came to be in this universe, it actually it what made our universe. When you think about physics you probably think about friction and forces but it is a much broader idea. Physics is what controls how the atoms that make up everything work with each other to form

A transformer is an electrical device that transfers electrical energy from one circuit to another circuit using inductively coupled conductors. In other words by putting two coils of wire close together while not touching, the magnetic field from the first coil called the primary winding effects the

THE NERVOUS SYSTEM
The nervous system allows the animal to quickly detect, communicate and co-ordinate information about its external and internal environment so it can make efficient appropriate responses for survival and/or reproduction.
The two major parts of our nervous system are the central nervous system (CNS) and peripheral nervous system (PNS).
The CNS is made of the brain and spinal cord.
The cranial nerves, spinal nerves and ganglia make up the PNS. The cranial nerves connect
