What is electrical energy? Give an example.

Specific examples of electrical energy include:

Alternating current (AC)

Direct current (DC)

Lightning

Batteries

Capacitors

Energy generated by electric eels

Explanation:

Electrical energy used for electric power, such as wall current used to power a light bulb or computer, is energy that is converted from electric potential energy. This potential energy is converted into another type of energy (heat, light, mechanical energy, etc). For a power utility, the motion of electrons in a wire produces the current and electric potential.

A battery is another source of electrical energy, except the electrical charges may be ions in a solution rather than electrons in a metal.

Biological systems also use electrical energy. For example, hydrogen ions, electrons, or metal ions may be more concentrated on one side of a membrane than the other, setting up an electrical potential that can be used to transmit nerve impulses, move muscles, and transport materials.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
