An apartment complex has a floor plan with the dimensions shown. To effectively air condition a room, 20BTU's (British Thermal U
marysya [2.9K]

The dimensions of the room is not given. Lets assume a value and calculate BTU accordingly.

Answer and Explanation:

BTU, or British Thermal Unit, is defined as the amount of heat required to raise the temperature of 1 pound of water by 1° F.

In other words,BTU's measures the amount of heat an AC (or any other cooling unit) can remove from a room per hour. Higher the BTU, the more powerful the cooling.

Calculation:

Lets assume that a room is 10 feet wide and 14 feet long.

  • Step 1

Calculate the size of the room by multiplying the height of the room with its width:

size of the room= 10 × 14

                          = 140 square feet

  • Step 2

Then multiply the size of the room that you obtained in step 1 with 20 BTU per square foot, in order to get the minimum BTU's required for AC to cool a room,

140 × 20= 2800

 2800 BTU cooling capacity is required.

MariettaO [177]

Answer:

Organism D.

Explanation:

Amino acids are the monomers of proteins and are linked together by the peptide bond. The protein is obtained from the RNA molecules by the process known as translation.

The amino acid sequence of the proteins can also be used to study the evolutionary relationship between the organisms and the closeness of teh organisms with each other. In the question it is give that organisms A and D has least difference ( 1 amino acid sequence difference) and more related with each other.

Thus, the answer is organism D.
