Explain why do conductors and insulators are both required to construct electrical wiring in your home

Physics

Dvinal [7]3 years ago

Conductors are needed because in order to get electricity in your home, the conductive substances need to transfer the energy from point A to point B. Insulation is needed around the conductor because you want the energy to stay in the conductive substance in order to bring it to the place where electricity is needed.

geniusboy [140]

We will apply the concept of period in a pendulum, defined as the product between 2\pi by the square root of the length over gravity, this is mathematically

T = 2\pi \sqrt{\frac{L}{g}}

Here,

T = Period

L = Length

g = Acceleration due to gravity

For the period to be 1 second, then we must look for the necessary length for such a requirement so

1 = 2\pi \sqrt{\frac{L}{9.8}}

(\frac{1}{2\pi})^2 = \frac{L}{9.8}

L = 9.8(\frac{1}{2\pi})^2

L = 0.2482m

The meter's length would be slight less than one-fourth of its current length. Also, the number of significant digits depends only on how precisely we know g, because the time has been defined to be exactly 1s.

Therefore the correct answer is C.

katrin2010 [14]

Answer:

2.1x10^6m/s

Explanation:

One electron has a charge of –1.602e-19 C

mass of electron is 9.1e-31 kg

mass of proton is 1.6726e−27 kg

mass ratio is 1.6726e−27 / 9.1e-31 = 1838

The force is constant, F

distance is constant, d

a = F/m

a increases by a factor 1838, as m decreases by that factor

a = a₀1838

v₀² = 2a₀d

v² = 2a₀d1838

v²/v₀² = 2a₀d1838 / 2a₀d = 1838

v² = 1838v₀² = 1838(45000)²

v = 45000√1838 = 2.1e6 m/s
