Questions and Answers

1.

What's an inlet?
- A.
  
  The pipelines
- B.
  
  The part of the tank filled with water
- C.
  
  A and B
- D.
  
  None of the above
Explanation
An inlet refers to the pipelines or openings that allow the flow of water or other substances into a tank or container. It is not the part of the tank filled with water, as that would be the interior or the body of the tank itself. Therefore, the correct answer is A.

Formula for getting a pipe filled by is x hours, so 1 hour the tank is filled by
- A.
  
  X/1
- B.
  
  2X/1
- C.
  
  1/x
- D.
  
  1/2x
Correct Answer
C. 1/x

Explanation
The formula for getting a pipe filled in x hours indicates that the rate at which the pipe fills the tank is 1/x. This means that in 1 hour, the tank is filled by 1/x.

Formula for emptying water from a tank of Y hours is
- A.
  
  1/y
- B.
  
  2y/1
- C.
  
  2Y/x
- D.
  
  3y
Correct Answer
A. 1/y

Explanation
The correct answer is 1/y. This formula suggests that the time it takes to empty a tank is inversely proportional to the number of hours, denoted by Y. In other words, as Y increases, the time it takes to empty the tank decreases. The fraction 1/y represents this relationship, where y is the number of hours it takes to empty the tank.

4.

What empties the water from the tank?
- A.
  
  Inlet
- B.
  
  Outlet
- C.
  
  Indoor
- D.
  
  A and B
Correct Answer
A. Inlet

Explanation
The inlet is the correct answer because it refers to the opening through which water enters the tank. Therefore, it is responsible for allowing water to flow into the tank and ultimately emptying it.

If a tank is emptied in J seconds into another tank in Z hours, what's the formula?
- A.
  
  1-1/4
- B.
  
  1/J-1/z
- C.
  
  6J-1
- D.
  
  None of the above
Correct Answer
B. 1/J-1/z

Explanation
The formula for the given scenario is 1/J - 1/Z, where J represents the time in seconds it takes to empty the tank and Z represents the time in hours it takes to fill the other tank. This formula calculates the rate at which the tank is being emptied and subtracts the rate at which the other tank is being filled, resulting in the net rate of emptying the tank.

What's the formula for surface, area
- A.
  
  2Πr^2
- B.
  
  2Πr^2+2Πrh
- C.
  
  A and B
- D.
  
  None of the above
Correct Answer
B. 2Πr^2+2Πrh

Explanation
The formula for finding the surface area of a cylinder is given by 2Πr^2+2Πrh. This formula takes into account both the area of the two circular bases (2Πr^2) as well as the area of the curved surface (2Πrh). Therefore, the correct answer is 2Πr^2+2Πrh.

7.

What's the volume of a pipe?
- A.
  
  2Πr^2
- B.
  
  2Π
- C.
  
  Πr^2h
- D.
  
  None of the above
Correct Answer
C. Πr^2h

Explanation
The volume of a pipe can be calculated using the formula Πr^2h, where r represents the radius of the pipe and h represents the height or length of the pipe. This formula is derived from the concept that the volume of a cylinder (which a pipe closely resembles) is equal to the area of the base (Πr^2) multiplied by the height (h). Therefore, the correct answer is Πr^2h.

Which is true, is TSA a solid shape term?
- A.
  
  True
- B.
  
  False
- C.
  
  Maybe
- D.
  
  I don't know
Correct Answer
A. True

Explanation
TSA stands for Transportation Security Administration, which is a government agency in the United States responsible for security in airports and other transportation systems. Therefore, TSA is not a solid shape term, but rather an acronym for an organization.

Which is another way of writing TSA?
- A.
  
  6x/y
- B.
  
  R+h
- C.
  
  2Πr(r+h)
- D.
  
  Option 4
Correct Answer
C. 2Πr(r+h)

Explanation
The correct answer, 2Πr(r+h), represents the formula for the lateral surface area (LSA) of a cylinder. LSA is the sum of the areas of all the curved surfaces of a cylinder, excluding the bases. In this formula, "r" represents the radius of the base of the cylinder, and "h" represents the height of the cylinder. The formula is derived by multiplying the circumference of the base (2Πr) by the height (h) of the cylinder.
