We all depend on electricity. Most electricity is created by electromagnetic generators at large power plants and distributed th

rough an electric grid. The electric grid in the United States is interconnected and includes more than 400,000 miles of electric transmission lines. However, the grid has not been well maintained, and the number and severity of power outages has been rising over the past decade. Because the grid is interconnected, a severe power outage in one area can quickly spread to other areas.
How long could you survive without electricity? What parts of your life would be affected by loss of electricity? Should you prepare for an electricity outage, and if so, how would you prepare? What backup system could your family or community install to generate limited amounts of electricity during an outage? How does this system create an electric force field and generate electric current?

Answer:

1) not so long (maybe an hour or two)

2) access to information through the internet will be most affected if my computer and mobile phone run out of battery power.

3) yes, one should prepare for power outage. This can be done by having a standby alternative source of power like the use of inverters that stores electrical energy in form of chemical energy, and small internal combustion engine powered electric generators.

4) solar panels can be used to draw power from incident sun rays, this power can be stored in an inverter for future use in case of a power outage.

5) energy from the sun is converted into direct current which is then supplied to an accumulator in the opposite direction to its flow of current. When the energy is needed, it can be used directly, or converted to an alternating current. This is achieved by connecting its terminal to the supply. Electric field is generated by flow of ions and electrons within the working chemical (e.g lithium).

A car ends up at x = -245 m after a displacement of -103 m. what was its initial position?
AysviL [449]

Answer:

-142m

Explanation:

To find the initial position of the car, we can add the displacement.

-245 + 103 = -142

Best of Luck!

Doubling an object’s height will have what effect on its potential energy due to gravity?
timurjin [86]
Potential energy due to gravity = Ep = mgh [symbols have their usual meaning ]
Evidently, HALVING the mass will make Ep , HALF its previous value. So, It will be halved.

A feather of mass 0.001 kg falls from a height of 2 m. Under realistic conditions, it experiences air resistance. Based on what
snow_tiger [21]

As per initial given conditions first we will find the initial potential energy of the feather

U = mgh

m = 0.001 kg

g = 9.8 m/s^2

h = 2m

U = (0.001kg)(9.8 m/s^2)(2m)

U = 0.0196 J

now we know that few amount of its initial energy is lost in form of frictional energy loss

so remaining energy will be less than the initial potential energy

So final answer would be

<u><em>A. KE < 0.0196 J</em></u>
