Answer:
The correct option is;
B. Neither Technician A nor B
Explanation:
A performance test is meant to determine the proper functioning of the air conditioning system for fault finding where repair is required
While the engine is powered off it is expected that to have the same pressure or equal pressures in the low-side and high-side pressure and have a pressure expected for a given ambient temperature, such that, as an example, a system with R134a should have a pressure slightly more than 71 psi. at 70°F
Therefore, neither technicians A nor B is correct as the ambient temperature is important for performance testing and high-side and low-side pressures should be equal when the engine is powered off.
Two technicians are discussing cylinder- testing. Technician A says that when testing the power level of a specific cylinder using a Power balance test, it's best to ground it's secondart current. Technician B says that it's best to disconnect one spark plugs wire at a time to test cylinder power levels. Who is correct?
Answer:
Technician B is the answer
BHE:FLI:JPM next sequence
Answer:
NTQ
Explanation:
The given sequence is
BHE : FLI : JPM
If is clear that, alphabets on first places are B, F, J. Difference between their place vales is 4.
B+4=F,F+4=J ; so alphabet on first place of next term of sequence is J+4=N.
Similarly, alphabets on second places are H, L, P. Difference between their place vales is 4.
H+4=L,L+4=P ; so alphabet on second place of next term of sequence is P+4=T.
Alphabets on third places are E, I, M. Difference between their place vales is 4.
E+4=I,I+4=M ; so alphabet on third place of next term of sequence is M+4=Q.
Therefore, the next term is NTQ.
The gear lube level is being checked in a manual transmission. Technician A says it should run out when the plug is removed. Technician B says that some transmissions use motor oil as gear lube. Who is correct?
Answer:
Both technician A and B are correct
Explanation:
The function of the gear lube drain plug is to drain the automatic transmission fluid from the gear box
Although motor oil is for the engine, motor vehicle transmission uses different oil types as the transmission system or automatic transmission system (ATF) operates in an closed system environment it is free from fuel contamination that motor oil absorbs
As such depending on the specification, manual transmission oil can range from hypoid oil, motor oil or automatic transmission oil.
answer this question fast
Answer:
When the expenditure increased, then the consumer's expenditure is increased to Rs.150 and when the price falls of the good it becomes Rs.5. Then, Good X will be Rs.10.
last question:If the Good X falls by 20%, then, it will be Rs.2, and according to his demand 100 units will be equal to Rs.200.
cause if one unit=rs.2, then 100units=100×2=200.
Am I the only one who cannot see the answers?? Does anybody know how to solve this?
Answer:
no, it seems that everyone is having the same issue. If you use the app you can still find the answers and see them.
Explanation:
If both the low-side and the high-side pressures are low, which of these could be the cause?
A. High refrigerant charge
B. Defective cooling fan
C. Low refrigerant charge
D. TXV. stuck open
Answer:
The correct option is;
C. Low refrigerant charge
Explanation:
Where both the low-side and the high-side pressure are low the refrigerant is low which may be as a result of a leak
When there is a low refrigerant charge there will be a larger range over which to compress the refrigerant increasing the work required and thus the heat in the system and the due to insufficient refrigerant, the entire system is under served and the evaporator super-heats due to lack of refrigerant
The liquid-line, the TVX evaporator and compressor will see less fluid flow and hence lesser pressures on the low-side and high-side of the refrigeration system.

Explanation:
The structure of a house is such that it loses heat ata rate of 3800 kJ/h per8C difference between the indoors andoutdoors. A heat pump that requires a power input of 4 kWis used to maintain this house at 248C. Determine the lowestoutdoor temperature for which the heat pump can meet theheating requirements of this house.
Answer:
The lowest outdoor temperature for which the heat pump can meet the requirement of the house is -9.6°C
Explanation:
The coefficient of performance of a heat pump, COP, is given by the relation;
[tex]COP_{hp} = \dfrac{T_2}{T_2 - T_1} = \dfrac{Q_1\times (T_2 - T_1)}{\Sigma W}[/tex]
The rate of heat loss [tex]\dot Q_1[/tex] = 3800 kJ/h = 3800 ×1/60 × 1/60 kJ/s = 1.06 kJ/s
The power input = 4 kW = 4 kJ/s
The temperature indoors = 24 + 273.15 = 297.15 K
Therefore, we have;
[tex]COP_{hp} = \dfrac{297.15}{297.15- T_1} = \dfrac{1.06 \times (297.15- T_1)}{4}[/tex]
4×297.15= (297.15- T₁) × 1.06×(297.15- T₁)
Which gives;
18/19·T₁²-627.32·T₁+92014.97=0
(T₁ -263.59)·(T₁ - 330.71) = 0
The solutions are;
T₁ = 263.59 K or T₁ = 330.71 K
The lowest temperature = 263.59 K which is -9.6°C
The lowest temperature = -9.6°C.
Royce has a Bevel protractor with a damaged vernier scale. What limitation will Royce face if he uses this protractor to measure angles?
Answer:
Limitation in the level of possible accuracy of the that can be obtained to mainly whole degrees
Explanation:
The angle measurement values are located around the circularly shaped bevel protractor to which a Vernier scale can be attached to increase the accuracy of the angle measurement reading
The accuracy of the bevel protractor is up to 5 arc minutes or 1/12° with the space on the Vernier scale having graduations of 1/12°, such that two spaces on the main scale is 5 arc minutes more than a space on the Vernier scale and the dimensions of the coincidence of the two scale will have an accuracy of up to 1/12°
Therefore, whereby the Vernier scale is damaged, the accuracy will be limited to the accuracy main scale reading in whole degrees.
