Sample Practice Test Questions

Automotive Information

Opposed cylinder designs feature two rows of cylinders that are placed at what angle to each other?

180°

Opposed cylinder designs place cylinders flat in two rows 180° opposite each other with a single crankshaft running between them.

Arithmetic Reasoning

What is \( \frac{4}{6} \) ÷ \( \frac{4}{8} \)?

1\(\frac{1}{3}\)

To divide fractions, invert the second fraction and then multiply:

\( \frac{4}{6} \) ÷ \( \frac{4}{8} \) = \( \frac{4}{6} \) x \( \frac{8}{4} \)

To multiply fractions, multiply the numerators together and then multiply the denominators together:

\( \frac{4}{6} \) x \( \frac{8}{4} \) = \( \frac{4 x 8}{6 x 4} \) = \( \frac{32}{24} \) = 1\(\frac{1}{3}\)

Electronics Information

The valence shell of a semiconductor is how full of electrons?

half full

Semiconductors have valence shells that are exacly half full and can conduct electricity under some conditions but not others. This property makes them useful for the control of electrical current.

Word Knowledge
Abate most nearly means:
subside
Become less in amount or intensity.
Word Knowledge
The repentant Dana admitted to cheating on the test.
contrite
Feeling regret.
Math Knowledge

Solve for c:
2c + 2 < 8 - 8c

c < \(\frac{3}{5}\)

To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the < sign and the answer on the other.

2c + 2 < 8 - 8c
2c < 8 - 8c - 2
2c + 8c < 8 - 2
10c < 6
c < \( \frac{6}{10} \)
c < \(\frac{3}{5}\)

Word Knowledge
Some consider Clint Eastwood the greatest extant American director.
living
Currently existing.
Word Knowledge
Flourish most nearly means:
brandish
To make bold, sweeping gestures.
General Science

The formula  \(\vec{F_{g}} = { Gm_{1}m_{2} \over r^2}\) applies to which of Newton's laws?

universal gravitation

Newton's law of universal gravitation defines gravity: All objects in the universe attract each other with an equal force that varies directly as a product of their masses, and inversely as a square of their distance from each other. Expressed as a formula:  \(\vec{F_{g}} = { Gm_{1}m_{2} \over r^2}\) where r is the distance between the two objects and G is the gravitational constant with a value of 6.67 x 10-11.

Arithmetic Reasoning

Convert 0.0006095 to scientific notation.

6.095 x 10-4

A number in scientific notation has the format 0.000 x 10exponent. To convert to scientific notation, move the decimal point to the right or the left until the number is a decimal between 1 and 10. The exponent of the 10 is the number of places you moved the decimal point and is positive if you moved the decimal point to the left and negative if you moved it to the right:

0.0006095 in scientific notation is 6.095 x 10-4
