Answer:
Malissa50 can you help me with my question please
Explanation:
List 3 disadvantages of Geothermal Energy and explain it in a point, example, explanation BEST ANSWER GETS BRAINLIEST!!!!
The entropy change<span> of the surroundings is driven by heat flow and the heat flow determines the sign of ΔS</span>surr<span>. It can be calculated by the following expression:
</span>ΔSsurr = -(ΔH) / T
We calculate as follows:
ΔSsurr = -13200 / 1337 = 9.87 J/ K mol
Hope this answers the question. Have a nice day.
Answer:
The magnitude of the net electric field is
Explanation:
Given that,
Charge density
Charge density
Distance
Distance
We need to calculate the magnitude of the net electric field
Using formula of electric field
Put the value into the formula
Hence, The magnitude of the net electric field is
To solve this problem it is necessary to apply the concepts related to Malus' law. Malus' law indicates that the intensity of a linearly polarized ray of light that passes through a perfect analyzer with a vertical optical axis is equivalent to:
Indicates the intensity of the light before passing through the Polarizer,
I = The resulting intensity, and
= Indicates the angle between the axis of the analyzer and the polarization axis of the incident light.
There is 3 polarizer, then
For the exit of the first polarizer we have that the intensity is,
For the third polarizer then we have,
Replacing with the first equation,
Therefore the transmitted intensity now is of the initial intensity.
Answer:
Explanation:
If
- , are temperatures of gasses and liquid in Kelvins,
- and are thicknesses of gas layer and steel slab in meters,
- , are convection coefficients gas and liquid in ,
- is the contact resistance in ,
- and are thermal conductivities of gas and steel in ,
then: part(a):
using known values:
part(b): Using the rate equation :
the surface temperature
and
Similarly
The temperature distribution is shown in the attached image
