Sample Practice Test Questions

General Science

Which of the following temperatures is least like the others?

32°F

Absolute zero is the coldest possible temperature in the universe. In the Kelvin scale, absolute zero is 0K and in the Celsius scale it is -273°C.

Electronics Information

Voltage and current are __________ proportional.

directly

Voltage (V) is the electrical potential difference between two points. Electrons will flow as current from areas of high potential (concentration of electrons) to areas of low potential. Voltage and current are directly proportional in that the higher the voltage applied to a conductor the higher the current that will result.

Shop Information

A __________ is driven by a motor and used to shape and form edge contours.

router

A router is a tool that a worker uses to rout (hollow out), shape, or contour an area in relatively hard material like wood or plastic.

Math Knowledge
21

If the base of this triangle is 6 and the height is 7, what is the area?

21

The area of a triangle is equal to ½ base x height:

a = ½bh
a = ½ x 6 x 7 = \( \frac{42}{2} \) = 21

Math Knowledge

Simplify 7a x 6b.

42ab

To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.

7a x 6b = (7 x 6) (a x b) = 42ab

Automotive Information

The fuel injectors are fed fuel by the:

electric fuel pump

The electric fuel pump feeds pressurized fuel through a fuel filter to the fuel injectors via the fuel rail manifold. The fuel rail contains the fuel pressure regulator which ensures that the fuel injectors receive fuel at a consistent and known rate. Excess fuel bled off by the pressure regulator returns to the fuel tank through the fuel return line.

Word Knowledge
Consuela's friends called her an aesthete when she claimed that Monet's paintings made her cry.
connoisseur
Person having or affecting sensitivity to beauty.
Math Knowledge
2\(\frac{1}{2}\)

The endpoints of this line segment are at (-2, -7) and (2, 3). What is the slope of this line?

2\(\frac{1}{2}\)

The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, -7) and (2, 3) so the slope becomes:

m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(3.0) - (-7.0)}{(2) - (-2)} \) = \( \frac{10}{4} \)
m = 2\(\frac{1}{2}\)

Math Knowledge

A coordinate grid is composed of which of the following?

all of these

The coordinate grid is composed of a horizontal x-axis and a vertical y-axis. The center of the grid, where the x-axis and y-axis meet, is called the origin.

Shop Information

Which of the following nuts prevent loosening via nylon in their threads?

lock

Wrenches are used with threaded fasteners like bolts and nuts. A bolt has external threads while a nut has internal threads and this thread pattern combination allows them to lock together and act as fasteners. Nuts come in a variety of configurations including wing nuts which provide appendages that allow tightening and loosening by hand, slotted nuts that use a cotter pin to lock the nut in place and prevent it from loosening, and lock nuts that also prevent loosening via nylon in their threads. Threads are identified by pitch which is the number of threads per inch.
