Answer:
Maximum allowable chip power is 0.35 W
Explanation:
This question is incomplete. The complete question is
A square isothermal chip is of width w = 5 mm on a side and is mounted in a substrate such that its side and back surfaces are well insulated; the front surface is exposed to the flow of a coolant at t[infinity] = 15°c. from reliability considerations, the chip temperature must not exceed t = 85°c. f the coolant is air and the corresponding convection 200 w/m2 k, what is the maximum allowable chip power?
<u>ANSWER:</u>
The heat transfer through convection, we have the equation:
q = hA(T - T∞)
where,
q = power transfer through convection = ?
h = convection coefficient = 200 W/m²K
A = Area of convection surface = (0.005 m)² = 0.000025 m²
T = Chip surface temperature = 85° C
T∞ = Fluid temperature = 15° C
Therefore,
q = (200 W/m².K)(0.000025 m²)(85° C - 15° C)
<u>q = 0.35 W</u>
Since, difference in temperature is same on both Celsius and kelvin scale. Therefore, Celsius is written as kelvin for difference and they shall be cancelled.
Answer:
Both are right.
Explanation:
I am obsessed with the manufacture of automobiles, and just did the quiz.
According to the research, research can facilitate the work of building technicians in the conception, materials to use and planning of the project.
<h3>What are building technicians?</h3>
They are experts in construction projects, supporting the design of plans, estimating costs, planning work methods, etc.
Research can facilitate the work of building technicians in the following ways:
- Conception, design and planning of the project.
- Selection of materials for floor, wall and ceiling systems.
- Carry out the programming of works, budgets and analysis of unit prices.
Therefore, we can conclude that according to the research, research can facilitate the work of building technicians in the conception, materials to use and planning of the project.

Answer:
Land use planning ensures that resources are used efficiently so that the needs of the people are met while safeguarding future resources. This planning process can be used to prevent land-use conflicts and reduce exposure to pollutants. Land use planning is essential for any development project.
