the majority of refrigeration systems in residential comfort cooling systems use what type of system?

DIA [1.3K]

Air conditioning, or cooling, is more complicated than heating. Instead of using energy to create heat, air conditioners use energy to take heat away. The most common air conditioning system uses a compressor cycle (similar to the one used by your refrigerator) to transfer heat from your house to the outdoors.

Picture your house as a refrigerator. There is a compressor on the outside filled with a special fluid called a refrigerant. This fluid can change back and forth between liquid and gas. As it changes, it absorbs or releases heat, so it is used to “carry” heat from one place to another, such as from the inside of the refrigerator to the outside. Simple, right?

Well, no. And the process gets quite a bit more complicated with all the controls and valves involved. But its effect is remarkable. An air conditioner takes heat from a cooler place and dumps it in a warmer place, seemingly working against the laws of physics. What drives the process, of course, is electricity — quite a lot of it, in fact. Hope this helps?

Answer:

D. 4x as much

Explanation:

The answer is pretty simple. The question is asking about 10m/s and 20m/s right? Take a look at the energy at each point on the graph. At 10m/s the kinetic energy is 100 on the graph. At 20m/s the kinetic energy is 400. You'll notice that 100 x 4 is 400 - That's the answer.

You can also prove this mathematically. The formula for kinetic energy is

$\frac{1}{2}mv^2$

The question says: constant mass so we can ignore that for now.

(1/2) * 10^2 is (1/2) * 100 = 50

for the 20m/s ball it would be

(1/2) * 20^2 = 400 * 1/2 = 200

Once again, you see that it is 4x

Answer:

plenipotentiaries. It was by far the most splendid and

important assembly ever convoked to discuss and

determine the affairs of Europe. The Emperor of

Russia, the King of Prussia, the Kings of Bavaria,

Denmark, and Wurttemberg, all were present in

person at the court of the Emperor Francis I in the

Austrian capital. When Lymie put down his fork and

began to count them off, one by one, on the fingers

of his left hand, the waitress, whose name was Irma,

thought he was through eating and tried to take his

plate away. He stopped her. Prince Metternich (his

right thumb) presided over the Congress, and

Prince Talleyrand (the index finger) represented

France? please let me know if this is the answer you were looking for!!

MAVERICK [17]

Well, I would say a web browser, like Mozilla Firefox, Safari for IOS, Windows Edge, Chrome, or Internet Explorer; and some anti-malware software, since there are multiple websites on the WWW that try to steal your information and give your device viruses.
