Answer:
1.52 x x (cm3 STP) / -s
Explanation:
This is a permeability problem ithat asked to compute the diffusion flux of water vapor through a 2-mm thick sheet of polypropylene. The permeability coefficient of H2O through PP is
38 x (STP)-cm / -s-Pa.
Thus, from Equation
J= x ΔP/Δx = x / Δx
here
P1= 2 kPa =2,000 Pa
P2= 11 kPa = 11,000 Pa
J = (38 X x (cm3 STP)(cm) / -s-Pa) (10,000 Pa - 2,000 Pa / 0.2 cm)
= 1.52 x x (cm3 STP) / -s
Answer:
Quadrants are counter-clockwise because angles are measured counter-clockwise; and angles are measured counter-clockwise so that Cross Product of unit vector in X direction with that in the Y direction has to be the unit vector in the Z direction (coming towards us from the origin).

Answer:
Both Technician A and Technician B are correct
Explanation:
Air tools and electric tools are both power tools as they are used to make work easier. Air tools generally use an air compressor that powers the motor of the tool making it possible to use it while electric tools as the name implies are powered by an electric source which in this case is batteries. An example of an air tool is the nail gun which can be used by furniture makers to drive nails and they are often louder than electric tools because of vibrations caused by the compressor making it necessary to use ear protection when using the tool for ear safety.
Technician B is also correct because it is always advisable to use impact sockets while using impact guns due to the ability of the impact sockets to withstand the force caused by operating impact guns and make work neater when nuts and bolts are being loosened or tightened.
Technician B only is right, who says that to avoid warping the cylinder head, the engine must be cold before removing it.
<h3>What is the cylinder head doing in my car?</h3>
The main task of the cylinder head is to close the discharge chamber of the engine from the top. The upper part of the engine is reached the cylinder head, while the lower part is the engine partnership.
The cylinder head sits on the engine and shuts off the combustion chamber. The gap that remains between the cylinder head and the engine is achieved by the head gasket.
<h3>How to recognize signs of possible defects</h3>
If you notice abnormalities in the functioning of your engine, it is advisable to contact a garage as soon as feasible to prevent further injury.
- The signs of cylinder head flaws include:
- You notice a power loss of the machine
- The cooling water temperature is in the red area
- You see oil in the cooling water
- You must supply water and oil after just a short time
- You notice a bad cold start behavior

complete question is,
Technician A only
Technician B only
Both A and B
Neither A nor B
The size conductor that should be used to supply each motor is 12 AWG and the size conductor that should be used for the feeder conductor is 1/0AWG.
<h3>Size conductor</h3>
a. Using NEC table 430.250
Running connect for 150HP connected to 460V = 21 A
Conductor size=25% current to 125% current (Increase)
Increase current=21×125/100
Increase current=26.25 A
Nearest standard conductor size using NEC table 310.15(B)(16)=25 A
Since the motor contain NEMA design code the conductor will be choosing from 75° column which means that the size conductor that should be used to supply each motor is 12AWG copper conductors.
b. Feeder conductor
Using NEC section 430.24 plus ampere rating of other motors
Running current
Using NEC Table 430.250
Running current=26.25+21+21+21+21+21
Running current=131.25 A
The value that is greater than 131.25 A under 75° column of NEC Table 310 (B)(16) is 150 A which means that the size conductor that should be used for the feeder conductor is 1/0 AWG conductors.
Therefore the size conductor that should be used to supply each motor is 12 AWG and the size conductor that should be used for the feeder conductor is 1/0AWG.
