Answer:

pls mark brainiest

Explanation:

Educational technology is an inclusive term for both the material tools and the theoretical foundations for supporting learning and teaching. Educational technology is not restricted to high technology but is anything that enhances classroom learning in the utilization of blended, face to face, or onlinelearning.First, the evolution of technology is beneficial to humans for several reasons. At the medical level, technology can help treat more sick people and consequently save many lives and combat very harmful viruses and bacteria. The invention of the computer was a very important point.

Indigenous is associated with people originating or developing naturally in a particular land, region, or environment. So the technology evolved by indigenous people are indigenous technology. Indigenous technology of India, will be the technologicaldevelopment caused by an Indian.

It helps shape and defines their very existence and provides the foundation for their beliefs and traditional practices. 3. Indigenous knowledge provides the basis for problem-solving strategies for local communities, especially the poor. It represents an importantcomponent of global knowledge on development issues.

There are important differences between the two

types of knowledge, although they are not easy

to locate unambiguously; this is probably because

we still know too little about traditional know-

ledge to define its scope and content accurately.

But in addition to the other ways of classifying

knowledge it may be useful to think of a three-

fold division of the uses to which knowledge is put: knowledge as a means of classification;

knowledge as a means of explanation and predic-

tion; and knowledge as a means of setting in motion rapid and cumulative change. There is

abundant evidence in most rural societies that the

first type of knowledge is well developed, and may be superior, in a functional sense, for

example to the Linnean system of classification.

There is some sign that the second category of

use of knowledge may be found in a rudimentary

way, but it does not seem to be well developed. The third category, fundamental to modern

science since Francis Bacon and Descartes, does

not appear to be found at all in the societies

with which we are concerned.

Modern technology would be things that we have today such as smart phones, tablets, gaming systems, and computers. Traditional technology would be things such as handicrafts that were made before things such as computers were invented.

examples are personal computers cell phones DVD recorders and players the electron microscope hydrogen fuel cells in cars hovercraft barcode scanners.

Example of modern technology..

modern technology is anything from a phone to a kindle. there is lots of technology.

the examples of technology is cellphone,television,computer,rice cooker,and other improve or high-tech materials at home.

WHAT are the example of modern technology..

computer..

What are examples of technology..

computers, laptops,mobiles,cars, airplane. ferryboat etc. u may think about chemistry technology, physic technology and biology technology etc.

A building window pane that is 1.44 m high and 0.96 m wide is separated from the ambient air by a storm window of the same heigh
sdas [7]

Answer:

the rate of heat loss by convection across the air space = 82.53 W

Explanation:

The film temperature

T_f = \frac{T_1+T_2}{2} \\\\= \frac{20-10}{2}\\\\= \frac{10}{2}\\\\= 5^0\ C

to kelvin = (5 + 273)K = 278 K

From  the " thermophysical properties of gases at atmospheric pressure" table; At T_f = 278 K ; by interpolation; we have the following

\frac{278-250}{300-250}= \frac{v-11.44(10^{-6})}{15.89(10^{-6})-11.44(10^{-6})}  → v 13.93 (10⁻⁶) m²/s

\frac{278-250}{300-250}= \frac{k-22.3(10^{-3}}{26.3(10^{-3}-22.3(10^{-3})} → k = 0.0245 W/m.K

\frac{278-250}{300-250}= \frac{\alpha - 15.9(10^{-6})}{22.5(10^{-6}-15.9(10^{-6})} → ∝ = 19.6(10⁻⁶)m²/s

\frac{278-250}{300-250}= \frac{Pr-0.720}{0.707-0.720} → Pr = 0.713

\beta = \frac{1}{T_f} \\=\frac{1}{278} \\ \\ = 0.00360 \ K ^{-1}

The Rayleigh number for vertical cavity

Ra_L  = \frac{g \beta (T_1-T_2)L^3}{\alpha v}

= \frac{9.81*0.00360(20-(-10))*0.06^3}{19.6(10^{-6})*13.93(10^{-6})}

= 8.38*10^5

\frac{H}{L}= \frac{1.44}{0.06} \\ \\= 24

For the rectangular cavity enclosure , the Nusselt number empirical correlation:

Nu_L = 0.42(8.38*10^5)^{\frac{1}{4}}(0.713)^{0.012}(24){-0.3}

NU_L= \frac{hL}{k}= 4.878

\frac{hL}{k}= 4.878

\frac{h*0.06}{0.0245}= 4.878

h = \frac{4.878*0.0245}{0.06}

h = 1.99 W/m².K

Finally; the rate of heat loss by convection across the air space;

q = hA(T₁ - T₂)

q = 1.99(1.4*0.96)(20-(-10))

q = 82.53 W

The performance of a heat pump degrades (i.e., its COP decreases) as the temperature of the heat source decreases. This makes us
vfiekz [6]

Answer:

COP_max = 18.69

Explanation:

We are given;

Heated space temperature; T_H = 26°C = 273K + 26 = 299K

Temperature at which heat is extracted; T_L = 10°C = 273 + 10 = 283K

Now the Coefficient of performance (COP) of a heat pump will be a maximum when the heat pump operates in a reversible manner. The COP of a reversible heat pump depends on the temperature limits in the cycle only and is determined by the formula;

COP_max = 1/(1 - (T_L/T_H))

Thus,

COP_max = 1/(1 - (283/299))

COP_max = 1/(1 - 0.9465)

COP_max = 1/0.0535 = 18.69
