Answer:

Crust, Upper mantle, mantle, outer core, inner core

Explanation:

The Earth's layers have been clasified in 5 according to the materials that conform them, theri physical properties, strengths and also their state of matter. We all know how the outer layer of the Earth looks like, but if we start to dig a huge hole we are going to see different types por materials due to a change in pressure, temperature, and other factors. At the very center of the Earth there's what's called "core". The core is liquid and at extremely high temperatures. This is because of the enormous amount of pressure the rest of the Earth is putting it under. So, if we list the different layers of the Earth according to the materials they are made of, from the Earth's surface to the core, the answer is:

1) Crust (surface)

2) Upper Mantle

3) Mantle

4) Outer core

5) Inner core

In some books you may find a layer called Lithosphere. Tis layer consists not only of the crust, but also it contains the transition zone between the upper mantle and the crust.

A 5200w electric oven​
OLga [1]

Answer:

104 kWh

Explanation:

To calculate the kWh you multiply power with the amount of hours.

So for this we take 5200 W × 20 = 104 000 Wh

Then change Wh to kWh so that makes 104 kWh

A stationary horn emits a sound with a frequency of 228 Hz. A car is moving toward the horn on a straight road with constant spe
stiks02 [169]

Answer: 26.84 m/s

Explanation:

Given

Original frequency of the horn f_o=228\ Hz

Apparent frequency f'=246\ Hz

Speed of sound is V=340\ m/s

Doppler frequency is

\Rightarrow f'=f_o\left(\dfrac{v+v_o}{v-v_s}\right)

Where,

v_o=\text{Velocity of the observer}\\v_s=\text{Velocity of the source}

Insert values

\Rightarrow 246=228\left[\dfrac{340+v_o}{340-0}\right]\\\\\Rightarrow 366.84=340+v_o\\\Rightarrow v_o=26.8\ m/s

Thus, the speed of the car is 26.84\ m/s

what is the energy required to melt down a 12,400g Gold bar assuming its temperature goes from 23c to 1,064c
sergejj [24]

1665183.6J

Explanation:

Given parameters:

Mass of Gold = 12400g

Initial temperature = 23°C

Final temperature = 1064°C

Unknown:

Energy required to melt = ?

Solution:

The amount of heat required to cause this temperature change to heat the gold bar is given as;

   H    =   m  c Ф

 m is the mass of gold bar

  c is the specific heat capacity of gold

  Ф is the heat change

 Specific heat capacity of gold = 0.129J/g°C

  H = m c (Ф₂ - Ф₁)

 H = 12400 x 0.129 x (1064 - 23) = 1665183.6J
