Answer: 16 squared + 63 squared = x squared
Explanation:
Hi, since we have a right triangle we have to apply the Pythagorean Theorem:
c^2 = a^2 + b^2
Where c is the hypotenuse of the triangle (the longest side) and a and b are the other sides.
Replacing with the values given:
x^2 = 63^2 + 16^2
So, the correct option is
16 squared + 63 squared = x squared

Answer:
The heat absorbed portion that is transformed into work is therefore helpful and accessible for our use, hence it is termed as available energy. But the energy or heat which is of no use is termed as unavailable energy.
Explanation:
A engine requires heat from the reservoir and transforms portion of it into function. The extra heat is expelled (generally atmosphere) to cold reservoir. The refused heat can't be equal to zero, as per the 2nd law of thermodynamics. The heat absorbed portion that is transformed into work is therefore helpful and accessible for our use, hence it is termed as available energy. But the energy or heat which is of no use is termed as unavailable energy.
Answer:
T2 ( final temperature ) = 576.9 K
a) 853.4 kJ/kg
b) 1422.3 kJ / kg
Explanation:
given data :
pressure ( P1 ) = 90 kPa
Temperature ( T1 ) = 30°c + 273 = 303 k
P2 = 450 kPa
Determine final temperature for an Isentropic process
----------- ( 1 )
T2 = 303 
= 576.9K
Work done in a piston-cylinder device can be calculated using this formula
------- ( 2 )
where : cv = 3.1156 kJ/kg.k for helium gas
T2 = 576.9K , T1 = 303 K
substitute given values Back to equation 2
= 853.4 kJ/kg
work done in a steady flow compressor can be calculated using this
where : cp ( constant pressure of helium gas ) = 5.1926 kJ/kg.K
T2 = 576.9 k , T1 = 303 K
substitute values back to equation 3
= 1422.3 kJ / kg
Answer:
"Test Phase
" is the correct choice.
Explanation:
- DevSecOps seems to be a community as well as experience of corporate data science which encompasses software design, regulation, including operational activities. This same main feature of DevSecOps has always been to strengthen customer achievement as well as expedition importance by computerizing, supervising as well as implementing data protection at all stages of the development including its development tools.
- The testing method throughout the test phase would then help make sure that the controller is designed mostly under the responsibilities forecasted. The test focuses on either the reaction times, dependability, use of resources but instead interoperability of applications.
