A branch circuit is supplying a single hermetic refrigerant motor-compressor for an air conditioning unit. The hermetic refrigerant motor-compressor rated-load current is 18 amperes. If a 30-ampere fuse will not start the motor-compressor, the maximum rating of the branch-circuit short-circuit and ground-fault protective device may be increased to ___.
Answers
The maximum rating of the branch-circuit short-circuit and ground-fault protective device for the hermetic refrigerant motor-compressor can be increased to 45 amperes to ensure it can handle the motor's inrush current during startup without tripping.
When determining the maximum rating of the branch-circuit short-circuit and ground-fault protective device for a hermetic refrigerant motor-compressor, it is essential to consider both the rated-load current and the starting current of the motor-compressor.
In this case, the hermetic refrigerant motor-compressor has a rated-load current of 18 amperes.
However, it is mentioned that a 30-ampere fuse will not start the motor-compressor.
This indicates that the motor-compressor has a higher starting current than its rated-load current.
Motor-compressors often experience inrush current during startup due to the high torque required to overcome the initial resistance and inertia.
This starting current is typically higher than the rated-load current and decreases once the motor-compressor reaches its operating speed.
To accommodate the starting current and ensure proper operation, it is common to use a protective device with a rating higher than the motor-compressor's rated-load current.
The National Electrical Code (NEC) provides guidelines for sizing protective devices based on the motor's starting characteristics.
According to NEC Table 430.52, the multiplier for determining the maximum rating of the protective device for a motor with a high inrush current is 250% of the motor's full-load current.
Applying this multiplier to the rated-load current of 18 amperes:
Maximum rating = 18 A * 250% = 45 A

The indirect tire-pressure monitoring system is being discussed between two technicians. A technician claims that certain automakers have employed it.
According to technician B, in order to identify a low tyre, the rotating speeds of the rf and lr tyres are compared. The fact that BOTH technicians are accurate should not be overlooked. Indirect tyre pressure monitoring systems are those that do not use air pressure sensors inside the tyres (TPMS). Instead, they analyse relative wheel revolutions using the ABS wheel speed sensors to detect a low tyre.

I found this on another site:
475,000 = 25,000(P/A,10%,6) + G(P/G,10%,6)
475,000 = 25,000(4.3553) + G(9.6842)
9.6842G = 366,117.50
G = $37,805.65
Answers
Answer:
G = $37,805.65
Explanation:
I found this on another site:
475,000 = 25,000(P/A,10%,6) + G(P/G,10%,6)
475,000 = 25,000(4.3553) + G(9.6842)
9.6842G = 366,117.50
G = $37,805.65

as the angle of the ramp is increased the force parallel increases /decreases / remains the same
Answers
As the angle of the ramp is increased, the force parallel increases. Hence, option (a) can be considered as the correct answer.
When the angle of a ramp is increased, the force parallel to the ramp, also known as the parallel component of the gravitational force, does increase. This is because the component of gravity acting parallel to the ramp increases with the angle. However, it's important to note that the total gravitational force acting on an object remains constant regardless of the angle of the ramp.As the angle of the ramp increases, the force required to push or pull an object up the ramp against gravity increases. This is due to the increase in the vertical component of the gravitational force, which opposes the motion up the ramp. The parallel force required to overcome this increased vertical force also increases.

Phosphorous is added to make an n-type silicon semiconductor with an electrical conductivity of 1.75 (Ωm)-1 . Calculate the necessary number of charge carriers required
Answers
Answer:
The necessary number of electron charge carriers required is:
8.1019 × 10¹⁹ electrons/m³
Explanation:
The necessary number of charge carriers required can be determined from the resistivity. Given that, the phosphorus make an n-type of silicon semiconductor;
Resistivity \(\rho = \dfrac{1}{\sigma}\)
\(\rho = \dfrac{1}{q \mu _n n_n}\)
where;
The number of electron on the charge carriers \(n_n\) is unknown??
The charge of the electron q = \(1.6 \times 10^{-19} \ C\)
The electron mobility \(\mu_n\) = 0.135 m²/V.s
The electrical conductivity \(\sigma\) = 1.75 (Ωm)⁻¹
Making \(n_n\) the subject from the above equation:
Then;
\(n_n = \dfrac{\sigma }{q \mu_n}\)
\(n_n = \dfrac{1.75 \ \Omega .m^{-1} }{1.6 \times 10^{-19} \times 0.135 \ m^2/V.s}\)
\(n_n =8.1019 \times 10^{19}\) electrons/m³
Thus; the necessary number of electron charge carriers required is:
8.1019 × 10¹⁹ electrons/m³
when does p-factor cause the airplane to yaw to the left? A. When at low angles of attack.
B. When at high angles of attack.
C. When at high airspeeds.
Answers
P-factor causes the airplane to yaw to the left when at high angles of attack.
What causes the airplane to yaw left at high angles of attack?P-factor, also known as propeller factor or asymmetric thrust, is a phenomenon that affects aircraft with a single rotating propeller. It occurs when the descending propeller blade on the right side of the aircraft's engine generates more thrust than the ascending blade on the left side during high angles of attack. This imbalance in thrust causes a yawing motion, resulting in the airplane yawing to the left.
At high angles of attack, where the aircraft's nose is pitched upward, the descending blade on the right side operates at a higher angle of attack relative to the oncoming airflow. This increased angle of attack generates more lift and thrust compared to the ascending blade on the left side, leading to an imbalance in forces. As a result, the aircraft experiences a left yawing moment.

for a mos transistor biased in the triode region we can define an incremental drain-source resistance as
Answers
The incremental drain-source resistance for a MOS transistor biased in the triode region is the ratio of the small change in drain current to the small change in gate voltage and is also dependent on the transistor's channel length, channel width, and oxide thickness.
For a MOS transistor biased in the triode region, the incremental drain-source resistance (also known as the "transconductance") can be defined as the ratio of the small change in drain current to the small change in gate voltage, ΔID/ΔVG. In other words, the transconductance is the change in drain current divided by the change in gate voltage.
The transconductance is also dependent on the transistor's channel length, channel width, and oxide thickness. For a given channel length and width, a longer oxide thickness will result in a lower transconductance, and vice versa. This is because a longer oxide thickness reduces the channel current, which in turn reduces the drain current.

Methanol is used in internal combustion engines. However, the use of methanol in internal combustion engines has decreased lately even though it was thought to lead to cleaner emissions than gasoline. Methanol internal combustion engines produce formaldehyde which is also an environmental pollutant. Also, the cost of methanol is slightly higher than that of good quality gasoline.
MTBE replaced tetraethyllead as a gasoline additive because the former lead to the emission of particulate lead from automobile exhausts which is a serious environmental pollutant. The use of MTBE has declined over the years due to environmental concerns. It has been banned because it has been found to be a significant groundwater pollutant if gasoline containing MTBE is spilled or leaked at gas stations.

A stream of refrigerant-134a at 100 psia and 30°F is mixed with another stream at 100 psia and 80°F. If the mass flow rate of the cold stream is twice that of the hot one and the pressure is not changed, determine the enthalpy of the exit stream in Btu/lbm (with three significant figures).
Answers
Answer:
The specific enthalpy of the exit stream is 63.267 Btu per pound-mass.
Explanation:
This case represents a mixing chamber, a steady state device where two streams of the same fluid (cold and hot streams) are mixed with negigible changes in kinetic and gravitational potential energy and likewise in heat work interactions with surroundings. By Principle of Mass Conservation and First Law of Thermodynamics we have the following Mass and Energy Balances:
Mass Balance
\(3\cdot \dot m_{in} - \dot m_{out} = 0\) (1)
Where:
\(\dot m_{in}\) - Mass flow of the hot stream, in pounds-mass per second.
\(\dot m_{out}\) - Mass flow of the resulting stream, in pounds-mass per second.
Energy Balance
\(2\cdot \dot m_{in}\cdot h_{c}+\dot m_{in}\cdot h_{H}-\dot m_{out}\cdot h_{out} = 0\) (2)
Where:
\(h_{c}\) - Specific enthalpy of the cold stream, in BTU per pound-mass.
\(h_{h}\) - Specific enthalpy of the hot stream, in BTU per pound-mass.
\(h_{out}\) - Specific enthalpy of the resulting stream, in BTU per pound-mass.
By applying (1) in (2) we eliminate \(\dot m_{in}\) and clear \(h_{h}\):
\(h_{out} = \frac{2\cdot h_{c}+h_{h}}{3}\)
From Property Charts of the Refrigerant 134a, we have the following information:
Cold fluid (Subcooled liquid)
\(p = 100\,psia\)
\(T = 30\,^{\circ}F\)
\(h_{c} \approx 37.870\,\frac{Btu}{lbm}\)
Hot fluid (Superheated steam)
\(p = 100\,psia\)
\(T = 80\,^{\circ}F\)
\(h_{h} = 114.06\,\frac{Btu}{lbm}\)
If we know that \(h_{c} \approx 37.870\,\frac{Btu}{lbm}\) and \(h_{h} = 114.06\,\frac{Btu}{lbm}\), then the specific enthalpy of the resulting stream is:
\(h_{out} = 63.267\,\frac{Btu}{lbm}\)
The specific enthalpy of the exit stream is 63.267 Btu per pound-mass.

and al, al
or al, 0
not al
Answers
The incorrect options for the program set the sign flag (SF) to 1 if the original value in al is negative, otherwise SF should be se to 0 is not al.
What is xor, and, or, not?
Xor, and, or, not is called as binary operation. Binary operation is operation to combine two binary number to produce another number.
To know the incorrect options we will evaluate each option,
For xor al, 0
The program is to xor-ing each value of al by 0. Xor result will be 1 if only single 1 in set. i.e.
0 xor 0 = 0
0 xor 1 = 1
1 xor 0 = 1
1 xor 1 = 0
So, this operation will keep the highest bit, and set the SF accordingly.
For or al, 0
The program is to or-ing each value of al by 0. Or result will be 1 except if both input is 0. i.e.
0 or 0 = 0
0 or 1 = 1
1 or 0 = 1
1 or 1 = 1
So, this operation will keep the highest bit, and set the SF accordingly.
For and al, al
The program is to and-ing each value of al by itself. And result will be 1 if only both input is 1. i.e.
0 or 0 = 0
0 or 1 = 0
1 or 0 = 0
1 or 1 = 1
So, this operation will keep the highest bit, and set the SF accordingly.
For not al
The program is to not-ing each value of al. Not result will be flipping the value. i.e.
not 0 = 1
not 1 = 0
So, this operation will flip the highest bit, and set the SF wrongly.

That means that the total amount earned by those 4 is;
4 x $17 = $68 per hour
(iii) The remaining people earn $16 per hour.
There are 7 people remaining. i.e
16 - 5 - 4 = 7
That means that the total amount earned by those remaining (7) is;
7 x $16 = $112 per hour
The total hourly wage is therefore the sum of all the results in i, ii and iii. i.e
Total = $75 + $68 + $112
Total = $255
Therefore, the total hourly wage earned by all 16 people is $255
