hi 1. Which of these is not correct as a basic property of electric charges? (a) Total charges in an insulated system is invariable (b) A charged body is electrically unstable (c) * A charged body has equal number of positive and negative charges (d) Positively charged body is deficient of electrons x+q1+q2 = 2 q1 2.Calculate the distance x between charges q1 and q2 shown‚ given the repulsive force between them as 1.2 x 10-4 N‚ take the permittivity of vacuum

to the consumer. The resistance of the wire used in the electrical grid distribution system causes a loss of 26-30% of the energy generated. This loss implies that our present system of electrical distribution is only 70-74% efficient. Nikola Tesla is best known for his remarkable statements regarding the wireless transmission of electrical power. His first efforts towards this end started in 1891 and were intended to simply "disturb the electrical equilibrium in the nearby portions of the earth

A French cyclotron‚ produced in Zurich‚Switzerland in 1937 A modern cyclotron for radiation therapy A cyclotron is a type of particle accelerator in which charged particles accelerate outwards from the center along a spiral path. The particles are held to a spiral trajectory by a static magnetic field and accelerated by a rapidly varying (radio frequency) electric field. History[edit] The

Chapter 4‚ page 1 4 Nuclear Magnetic Resonance Pieter Zeeman observed in 1896 the splitting of optical spectral lines in the field of an electromagnet. Since then‚ the splitting of energy levels proportional to an external magnetic field has been called the "Zeeman effect". The "Zeeman resonance effect" causes magnetic resonances which are classified under radio frequency spectroscopy (rf spectroscopy). In these resonances‚ the transitions between two branches of a single energy level

his invention -- the electric light bulb. Prior to 1879‚ direct current (DC) electricity had been used in arc lights for outdoor lighting. In the late-1800s‚ Nikola Tesla pioneered the generation‚ transmission‚ and use of alternating current (AC) electricity‚ which can be transmitted over much greater distances than direct current. Tesla ’s inventions used electricity to bring indoor lighting to our homes and to power industrial machines. Despite its great importance in our daily lives‚ most of us

don’t soon forget it. The mix between magic and science in this science fantasy animation proves to be hardly homogenous. The story quickly jumps from one genre element to the next with very little warning such as the renaissance style fair full of tesla coils and other green glowing science objects to fight scenes of Blackheart shooting down a volley of arrows with a massive laser cannon. While there is often a large contrast between the elements of fantasy and science in the movie‚ they are also often

available parts. It is easy to build and easy to use and is capable of many metal heating applications. The particular heater shown here was designed for heating "getters" and electrodes in gas discharge lamp assemblies. The result is that the work coil is attached to the electronics box. It could easily be located in a "wand" at the end of a cable.I’m going to assume that you’ve read Richie’s page that covers the theory of induction heating and specifically
