In places with cold winters, space heating systems have a fundamental role in buildings. Without them, indoor temperatures would quickly become unsuitable for human occupancy. The local weather is one of the most important factors when designing a heating system; if two identical buildings are developed in Miami FL and New York City, the heating load will be much higher for the NYC property.

A particular NMOS device has parameters VT N = 0.6 V, L = 0.8µm, tox = 200 Å, and µn = 600 cm2 /V–s. A drain current of ID = 1.2
NeTakaya

Answer:

W= 3.22 \mu m

Explanation:

the transistor In saturation drain current region is given by:

i_D}=K_a(V_{GS}-V_{IN})^2

Making K_a the subject of the formula; we have:

K_a=\frac {i_D} {(V_{GS} - V_{IN})^2}

where;

i_D = 1.2m

V_{GS}= 3.0V

V_{TN}  = 0.6 V

K_a=\frac {1.2m} {(3.0 - 0.6)^2}

K_a = 208.3 \mu A/V^2

Also;

k'_n}=\frac{\mu n (\frac{cm^2}{V-s} ) \epsilon _{ox}(\frac{F}{cm} ) }{t_{ox}(cm)}

where:

\mu n (\frac{cm^2}{V-s} ) = 600

\epsilon _{ox}=3.9*8.85*10^{-14}

{t_{ox}(cm)=200*10^{-8}

substituting our values; we have:

k'_n}=\frac{(600)(3.988.85*10^{-14})}{(200*10^{-8})}

k'_n}=103.545 \mu A/V^2

Finally, the width can be calculated by using the formula:

W= \frac{2LK_n}{k'n}

where;

L = 0.8 \mu m

W= \frac{2*0.8 \mu m *208.3 \mu}{103.545 \mu}

W= 3.22 \mu m

Gina is about to use a fire extinguisher on a small fire. What factor determines the
Effectus [21]

Answer:

Each portable fire extinguisher should only be used for its specific type of fire. Class A extinguishers could cause a Class B fire to spread or electrocution in a Class C fire. A Class B extinguisher could fail to completely extinguish a Class A fire, causing the flame to re-ignite later.
