Answer:
Electric force is a phenomenon which is experienced by a point charge due to its presence in an electric field. Electric force fields indicate the strength of the electric force that will be experienced, and also the direction of the force. The strength is shown by the closeness of the electric field lines and the direction is shown by the direction of the lines. Therefore, force fields are necessary in describing electric force.
Well it would not be c as it wouldn't be a transmitter. Since it's a power plant it wouldn't be Transmitter, and heated water makes steam it has to be B Steam, Turbine.

4.472 tonnes of coal burned
Explanation:
The electricity consumption for a typical house in the United States for a year is approximated as 11,000 kWh.
Given that a typical coal-fired power plant produces 2,460 kWh of electricity per ton of coal burned then;
2460 kWh = 1 ton of coal burned
11,000 kWh =?
cross-product
(11,000*1)÷ 2460 = 4.472 tonnes of coal burned

Explanation:
Given that:The brief pulses of energy absorbed by the retina welds the detached portion back into place. In one such procedure, a laser beam has a wavelength of 810 nm and delivers 250 mW of power spread over a circular spot 510 μm in diameter. The vitreous humor (the transparent fluid that fills most of the eye) has an index of refraction of 1.34.A) If the laser pulses are each 1.5 ms, long, how much energy is delivered to the retina with each pulse?B) What average pressure does the pulse of the laser beam exert on the retina as it is fully absorbed by the circular spot?C) What is the wavelength of the laser light inside the vitreous humor of the eye?D) What is the frequency of the laser light inside the vitreous humor of the eye?E) What is the maximum value of the electric field in the laser beam?F) What is the maximum value of the magnetic field in the laser beam.
