Answer:

We can say that electromagnet is coils of wire which behave like bar magnets with a distinct South and North poles when a current of electricity passes through the coil.

The bigger the strength of Ryan's electromagnet, the better the conductivity of the material.

The material is as follows,

1. Silver and it is the best conductor.

2. Iron.

3. Nickel

4. Steel.

5. Glass which is an insulator, and

6. wood which is an insulator, and we thoroughly know that insulators they don't conduct electricity.

Explain how climbing a mountain is similar to hiking from the equator to one of the poles
Igoryamba

Explanation:

  • Climbing a mountain is similar to hiking from the equator to the pole because in both cases temperature decreases.
  • The higher you go, the cooler it becomes.
  • For a certain elevation, there is particular drop in temperature. High altitudes offers cooler temperatures.
  • The equator receives a huge insolation and the sun is overhead there.
  • It implies that the temperature is always high around the equatorial region.
  • As one increases latitude, the temperature drops and its is coldest at the pole.
  • In both cases, temperature drops and it gets colder.

If the surface temperature of that person's skin is 30∘C (that's a little lower than healthy internal body temperature becaus
anastassius [24]

Answer:

E=477.92\ W.m^{-2}

Explanation:

Given that:

Absolute temperature of the body, T=273+30=303\ K

  • emissivity of the body, \epsilon=1

<u>Using Stefan Boltzmann Law of thermal radiation:</u>

E=\epsilon. \sigma.T^4

where:

\sigma =5.67\times 10^{-8}\ W.m^{-2}.K^{-4}   (Stefan Boltzmann constant)

Now putting the respective values:

E=1\times 5.67\times 10^{-8}\times 303^4

E=477.92\ W.m^{-2}

Which of the following best describes a capacitor?
galben [10]

Answer:

B

Explanation:

The capacitor is a component which has the ability to store energy in the form of an electrical charge  making a potential difference on those two metal plates

A capacitor consists of two or more parallel conductive (metal) plates. They are electrically seperated by an insulating material (ex: air, mica,ceramic etc.) which is called as Dielectric Layer

Due to this insulating layer, DC current can not flow through the capacitor.But it allows a voltage to be present across the plates in the form of an electrical charge.

The loudness of a sound is inversely proportional to the square of your distance from the source of the sound. if your friend is
kirill [66]
Let loudness be L, distance be d, and k be the constant of variation such that the equation that would best represent the given above is,
                    L = k/(d^2)
For Case 1,
                       L1 = k/(d1^2)
For Case 2,
                       L2 = k/((d1/4)^2)
For k to be equal, L1 = 16L2. 
Therefore, the loudness at your friend's position is 16 times that of yours.
