Answer:
Iron
Explanation:
Once a star starts fusing iron in its core it gives off very large amounts of energy. Also helium, hydrogen, carbon, oxygen, and silicon still exist in the star in different shells while fusin is taking place at different parts of the star. Right at the surface, hydrogen continues to fuse to helium, as e go further down helium is fusing to carbon and oxygen; right inside the core we have silicon that is fusing with iron. At this point, Iron being of stable atomic structure and quite heavier will no longer be fused into anything because of the quite large amounts of energy and force required to fuse iron atoms. The process comes to a standstill at this point.
Answer:
<em>The maximum efficiency the plant will ever achieve is 75%</em>
<em>Explanation:</em>
From the question given, we recall the following:
<em>Th flames in the boiler reaches a temperature of = 1200K</em>
<em>the cooling water is = 300K</em>
<em>The maximum efficiency the plant will achieve is defined as:</em>
Let nmax = 1 - Tmin /Tmax
Where,
Tmin = Minimum Temperature in plants
Tmax = Maximum Temperature in plants
The temperature of the cooling water = Tmin = 300K
The temperature of the flames in boiler = Tmax = 1200k=K
The maximum efficiency becomes:
nmax = 1 - Tmin /Tmax
nmax = 1 - 300 /1200
nmax = 1-1/4 =0.75
nmax = 75%
The software industry is evolving, and software certification is crucial. Software certification is a digitally signed certificate that verifies the identification of an individual or company.
<h3>What is software certification?</h3>
A certificate, sometimes known as a digital certificate, is a special document that has been digitally signed and authenticates the identity of a person or business.
Its validity may be checked using public-key cryptography to make sure that the program or website you are accessing is reliable.
Software developers must demonstrate that their program executes the XBRL conformance suites successfully in order to be certified.
They must also supply extra test cases so that XBRL employees can test the program further. The validity of certification is one year, renewable yearly.
Hence the software industry is evolving, and software certification is crucial.

Answer:
Uair = 0.0749 KW/k = 74.9 W/k
Explanation:
The natural air change per hour is given by the formula:
Natural Air Change per Hour = ACPH = 60*Volume Flow/Volume
where,
ACPH = 0.4
Volume Flow = ? in ft³/min
Volume = 19456 ft³
Therefore,
0.4 = (60 min)(Volume Flow)/(19456 ft³)
Volume Flow = (0.4)(19456 ft³)/(60 min) = (129.7 ft³/min)(1 min/60 s)
Volume Flow = (2.16 ft³/s)(0.3048 m/1 ft)³ = 0.061 m³/s
Now, we find heat loss coefficient:
Uair = Volumetric Flow*Density of air*Specific Heat Capacity of air
Uair = (0.061 m³/s)(1.225 kg/m³)(1 KJ/kg.k)
<u>Uair = 0.0749 KW/k = 74.9 W/k</u>
Answer:
The first step of the problem solving process is to identify and define the problem. The second step, which is to analyze the problem, involves gathering information, sorting through relevant and irrelevant information, and evaluating the source of the problem by asking the Five W's: who, what, where, when, and why.
