What countries could benefit most from solar energy

Physics
1 answer:
Alecsey [184]3 years ago

Countries longer day for example in the Middle East could benefit more but Alaska has more night like longer night which is why it would hard to benefit from the solar panels there.

Answer:

not captured for use by living things

Explanation:

The sun is a star with a high radiation and most of(around 55-67%) the radiation that reaches the earth is usually reflected back. The earth cannot use all the energy that reaches the earth. It uses almost around 15-30%

The distance between the plates is 7.1 * 10^-7 m

<h3>What is the distance?</h3>

The capacitor is a device that is used to store charges. The capacitor always has a dielectric that is placed between the capacitors that separates them.

Given that;

C = εoA/d

C = capacitance

εo = permittivity of free space

A = cross sectional area

d = distance apart

Cd = εoA

d = εoA/C

d = 8.8 * 10^-12 * 8.89 * 10^-4/1.11 * 10^-8

d = 7.1 * 10^-7 m

A Carnot engine operates between two heat reservoirs at temperatures TH and TC. An inventor proposes to increase the efficiency
Dovator [93]

Answer:

A) Efficiency = 1 - (TC/TH)

B) Comparing this with the efficiency of the original carnot engine, the efficiency is the same

Explanation:

The formula for efficiency of an original carnot engine is;

e = 1 - T(C) /T(H) ——— eq 1

In like manner, for a composite engine, the efficiency is;

e(12) = (W1 + W2)/Q(H1)

Where W1 is work done by 1st engine; W2 is work done by second engine and Q(H1) is the heat input to the first engine.

Now the total work done is;

W = Q(H) + Q(C)

Where Q(H) is the heat input and Q(C) is the heat released.

Thus,

e(12) = [Q(H1) + Q(C1) + Q(H2) + Q(C2)] / Q(H1)

Now, from the earlier e(12) equation compared to this, QH2 = -QC1

Thus;

e(12) = [Q(H1) + Q(C1) - Q(C1) + Q(C2)] / Q(H1)

So e(12) = [Q(H1) + Q(C2)] / Q(H1)

So e(12) = 1 + [Q(C2)/Q(H1)] ———eq 2

Also,

Q(C2) /Q(H2) = (-Tc/T')

Where T' is intermediate temperature.

So, simplifying that,

Q(C2) = -Q(H2) (Tc/T')

This is also equal to Q(C1) (TC/T')

But Q(C1) is also equal to;

-Q(H1) (T'/TH)

Thus; Q(C2) is now written as;

Q(C2) = -Q(H1) (T'/TH)(TC/T')

So T' will cancel out to remain;

Q(C2) = -Q(H1)(TC/TH)

Replacing this with Q(C2) in eq 2 to obtain;

e(12) = 1 + [[-Q(H1)(TC/TH)] /Q(H1)]

e(12) = 1 - TC/TH
