Electric string instruments use electrical signals and amplifiers to increase an instrument’s volume and modify its sound. Composers from all genres of music have used electric instruments in their compositions. While electric instruments more commonly appear in rock and popular music the classical composer George Crumb wrote a composition for electric strings entitled “Black Angels.” Electric string instruments are not the same as semi-acoustic instruments that use a mixture of sound boxes and electric

Why is magnetic flux through closed surface zero while electric flux not? Gauss’ Law for Magnetism The net magnetic flux out of any closed surface is zero. This amounts to a statement about the sources of magnetic field. For a magnetic dipole‚ any closed surface the magnetic flux directed inward toward the south pole will equal the flux outward from the north pole. The net flux will always be zero for dipole sources. If there were a magnetic monopole source‚ this would give a non-zero area integral

An electric car is powered by an electric motor instead of a gasoline engine. The electric motor gets energy from a controller‚ which regulates the amount of power transmitted throughout the vehicle‚ based on the driver’s use of an accelerator pedal. The electric motors give electric cars instant torque‚ creating a strong and smooth acceleration pattern. Electric cars are about three times more efficient than cars with an internal combustion engine. A pure-battery electric car uses energy stored

The History of the Electric Guitar The desire to increase the sound of the guitar existed long before the development of electrical amplifiers and speakers. Musical performances in the 19th century were characterized by ever-larger concert settings and ensembles. Musicians needed louder and more powerful instruments‚ which became possible by using new materials and designs. The introduction of steel strings in the 19th century meant not only greater volume‚ but greater tension on instruments

Heat: a form of energy Heat In physics and chemistry‚ heat is energy transferred from one body to another by thermal interactions.[1][2] The transfer of energy can occur in a variety of ways‚ among them conduction‚[3] radiation‚[4] and convection. Heat is not a property of a system or body‚ but instead is always associated with a process of some kind‚ and is synonymous with heat flow and heat transfer. Heat flow from hotter to colder systems occurs spontaneously‚ and is always accompanied by an

The Lincoln Electric Case International Strategic Management By: Group 4A Introduction John C. Lincoln founded the Lincoln Electric Company in the year 1895. The first products that the company produced and sold were electric motors that he had designed himself. A Few years later‚ in 1907 his brother James‚ a recently graduate from the Ohio State University‚ joined as a senior manager; He was also the one who would introduce different and very innovative human resource policies

The Lincoln Electric Company‚ 1996 Background The Lincoln Electric Company is a leading manufacturer of arc-welding and cutting products. Founded by John C. Lincoln in 1895‚ Lincoln Electric began its business with the design of electric motors. John’s younger brother‚ James‚ joined the company in 1909 as a salesman. Almost twenty years after founding the company‚ John C. Lincoln decided to concentrate on being an engineer and inventor‚ and turned the duties of running the company to his brother
