The answer to the question will be C
Both the Technicians A and B are somewhat correct in their statements about an automotive air conditioning system. The accumulator will generally be warmer than the orifice tube, and the inlet to the compressor should indeed be cooler than the outlet.
Explanation:In an automotive air conditioning system, both statements made by Technicians A and B are correct to certain extents. If we have a system with an orifice tube, then Technician A is correct that the accumulator temperature will generally be higher than the orifice tube temperature after the system has been running because the orifice tube cools the refrigerant before it goes to the evaporator. This is what cools the air going into the cabin of the car.
Technician B is also correct because in a properly functioning system, the inlet to the compressor (which is taking in low-pressure gas from the evaporator) should indeed be cooler (since this gas has just absorbed heat energy from the interior air of the vehicle) whereas the outlet from the compressor (which is discharging high-pressure gas to the condenser) should be hot (since the compressor is now injecting mechanical energy into this gas, thus heating it).

A teacher attaches a ball to a meter long string and whirls it around in a horizontal circle at constant speed. The teacher explains that the string is what makes the ball go in a circle. Why is the string necessary? A) The string is needed to apply a torque to the ball. B) The string is needed to push on the ball to get it up to speed. C) Circle motion requires an inertia which is provided by the string. D) Circle motion requires a force to give it a centripetal acceleratio
The string provides the necessary centripetal force to maintain the ball in circular motion. Without the string, the ball would proceed in a straight line due to inertia.
Explanation:The string is necessary when a teacher whirls a ball around in a horizontal circle at constant speed because for an object to maintain circular motion, there must be a centripetal force acting towards the center at all times. Option D is correct. This centripetal force is provided by the tension in the string, which always acts towards the center of the circle. Without the string, no such inward force would exist, and the ball would not follow a circular path but instead would move off in a straight line according to Newton's first law of motion (the law of inertia).
Once the ball has reached a constant speed in its circular path, the only force necessary to maintain this motion is directed inward—which the string provides. The idea that the force needs to be at an angle during constant circular motion is a common misunderstanding; only an initial angle is needed when getting the ball up to speed. As per Newton's third law, the action force is the tension from the string on the ball, and the reaction force is that of the ball's mass pulling back on the string.
DNA is a polymer of __________, which consist of a sugar, a phosphate group, and a __________. A. amino acids; nucleotide
B. nucleic acids; nucleotide
C. nucleotides; nitrogenous base
D. nucleotides; nucleic acid E. proteins; nucleotide
Answer: C
It can't be A because there are no nucleic acids in DNA polymers
It isn't B because DNA is a polymer of nucleotides of MONOmers that are nucleic acids.
It can't be D because the 3 parts of a nucleotide is a sugar, nitrogenous bases(adenine, guanine, thymine, and cytosine), and a phosphate group.
It cannot be E because there are no proteins in nucleotides.
Answer C is the only answer that fit the sentence perfectly.
the correct answer is c
If the “exact” terms of the listing agreement are met, the listing broker is entitled to a commission, even if the:
Answer:
even if the client goes with a different real estate broker.
Explanation:
if client decides to purchase property thru a different broker other than listing agent, that broker is entitled to 3-4% commission...
The correct answer to this open question is the following.
If the “exact” terms of the listing agreement are met, the listing broker is entitled to a commission, even if the owner does not accept to sell the property.
In this case, if all the requirements were covered and all the requests were met the broker deserves a commission of around 3%. In Real State, the term listing means the contract to employ a broker as an agent and help in the process to get the best option for the client, in this case, the person who sells the property. It serves as a contract for professional services.
