Which of the following should maintain the appropriate temperature and humidity levels and provide closed-loop recirculating: a.
Diano4ka-milaya [45]

If we define each of the systems that are given in the options we will have to:

Air conditioning is the air treatment that modifies its conditions to suit certain needs, i.e., the process of removing heat and moisture from the interior of an occupied space to improve the comfort of occupants. Air conditioners are also responsible for controlling humidity in closed rooms.

Positive Pressurization is a pressure within a system that is greater than the surrounding environment. Consequently, if there is any leakage of the system with positive pressure, it will leave the surrounding environment. There is no temperature or humidity control here

Ventilation is done by artificially creating depressions or overpressures in air distribution ducts or building areas. The fans are mechanically responsible for increasing the volume flow of air in a system. Moisture is not controlled directly.

Therefore the correct answer is A.

2. In contrast to Venus, the coldest temperature yet measured on the surface of
garik1379 [7]

Answer:

Explanation:

<u>Temperature Scales </u>

There are three temperature scales in the modern sciences: Fahrenheit, Celsius, and Kelvin. Fahrenheit temperature scale assigns the value 32 for the freezing point of water and 212 for the boiling point of water and divides that interval into 180 parts. Celsius scale has a similar reference, giving 0 to the freezing point of water and 100 for the boiling point of water. The conversion between them is as follows

\displaystyle F=\frac{9}{5}C+32

K=C+273.15

The coldest temperature yet measured on the surface of any body in the solar system is -235°C. Converting to Fahrenheit

\displaystyle F=\frac{9}{5}(-235)+32=-391^oF

K=-235+273.15=38.15^oK

1. An object 20 cm away from a lens produces a focused image on a film 15 cm away, what is the focal length
morpeh [17]

8.6 cm

Explanation:

Step 1:

In this we have to find the focal length of converging lens.

To find focal length we have,

(1/u) + (1/v) = (1/f)

where u = Object distance

           v= Image distance

           f = Focal length

Step 2:

(1/f) = (1/20) + (1/15)

(1/f) =  0.116

f = 1/0.116

f = 8.6 cm
