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.
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
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.
Lunar phases are basically the different positions of the moon that we see throughout its whole cycle, from new moon to full moon, back to new moon. Eclipses, though are more rare phenomena. These occur when the sun, moon, and earth line up at a specific position.
Asteroids are usually dense bodies, with many different formations on their surface. They are also believed to be the largest source of precious metals on our planet.
Comets are bright clouds of gas surrounding a center nucleus that speed toward the sun and heat up at the same time. They contain dust, ice, carbon dioxide, and other gases. As the comet soars toward the sun, the radiation pushes dust particles back, forming the tail they are known for.
Answer: The x-axis has mother bird and the y-axis has chicks
Explanation:
The researchers studying the relationship between the number of eggs which is laid by the birds and the number of chicks which is surviving at the end of the year.
The researchers will make a graph between these two factors. One is eggs laid and the number of chicks that survived till the year last.
This will help to known of the proportion of the chicks which survived on an average.
He used Selective Breeding
