Diode logic gates are not suitable for cascading operation because the pull-down or pull-up resistance within makes them a high output resistance device.
<h3>What is a
cascading operation?</h3>
A cascading operation refers to a process in electrical engineering which involves the use of a circuit breaker's current-limiting capacity, so as to enable an installation of lower-rated and lower-cost circuit breakers.
According to the National Electrical Code (NEC), diode logic gates are not entirely suitable for cascading operation due to the fact that the pull-down or pull-up resistance within makes them a high output resistance device.

Answer:
The velocity the air will enter the room through an opening is 20.9
Explanation:
We have to consider 2 points
Point 1 = Being away from the laboratory door
Point 2 = Gab between the floor and the laboratory door
Using the Bernoulli equation
Assuming
p1 = patm
p2 = patm + plab
patm will be cancel and both points will be at the ground level
= - у H2O * hH2O
Substituting the results
V2 = 20.9
Answer:
The area of solar panel needed in Buffalo is 22.83 m²
The area of solar panel needed in Phoenix is 31 m²
Explanation:
<u>FOR BUFFALO</u>:
First we, calculate the the annual power requirement by dividing the energy by the time of 1 year.
Therefore,
Power Requirement = P = 6000 KWhr/(1 yr)(365 days/yr)(24 hr/day)
P = 684.93 W
Now, to calculate the area we use the formula:
Area = A = P/(Annual Insolation)(Conversion Factor)
A = 684.93 W/(200 W/m²)(0.15)
<u>A = 22.83 m²</u>
<u>FOR PHOENIX</u>:
First we, calculate the the annual power requirement by dividing the energy by the time of 1 year.
Therefore,
Power Requirement = P = 11000 KWhr/(1 yr)(365 days/yr)(24 hr/day)
P = 1255.7 W
Now, to calculate the area we use the formula:
Area = A = P/(Annual Insolation)(Conversion Factor)
A = 1255.7 W/(270 W/m²)(0.15)
<u>A = 31 m²</u>

Answer:
A. Manufacturers rating capacity ↔ 3. Must be marked on all jacks; must not be exceeded
B. Block Used to lift and hold heavy loads, allow them for travel ↔ 1. Place the jack head against this
C. Level surface ↔ 4. Place this under the base of the jack when it's necessary to provide a firm foundation
D. Jack ↔ 2. Used to lift and hold heavy loads, allow them for travel
Explanation:
The manufacturers rating for a jack is labelled on all jacks and should be referenced to compare with the load to be lifted so as to ensure a safe and successful lifting.
In order to lift a load, such as a car, it is required to place the jack on a level surface to provide balance during the lifting task
The head of the jack is placed against the block for lifting heavy objects for proper performance
Answer:
b) False
Explanation:
Work done by a system is not a property because it doesn't define the system's state. Work is mechanical energy exchanged across the system's boundaries.
