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

The test charge at first was attracted but then repelled. 3. After observing the electric field in your trials above‚ where was the electric field the strongest? What was the direction of the electric field? ● Positive charge Upwards 4. Did you notice a green arrow appear as the test charge started to accelerate‚ this arrow represented the electric force! If not‚ take another “shot” at the game above and come back to this question. When was the electric force the greatest? ● Electric force was the greatest when the positive/negative was close to the test charge

Ch.9.1 – Types of Electric Charge * Static electricity : static cling of clothes out of dryer; lightning; * Walk across carpet and touch get a shock touching metal doorknob – friction of shoes against carpet cause you acquire static electric charge * Static charge – electric charge at rest‚ stays on and eventually discharged or lost to other objects/air * Discharge – remove excess static charge so the object is neutral * Static charge last long when air is dry * Electrostatics

maintains competitive input pricing. However‚ the electric vehicle (EV) industry demonstrates a different type of dynamic. Consumer power is middling‚ due to slightly higher switching costs and the limited selection of mass produced EVs currently available. The threat of new entrants is much greater since both traditional automakers are entering the electric market‚ complemented by an ever-increasing number of start-ups. Around 1890‚ the first American electric car powered by 24 batteries had a range of

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
