Sample Practice Test Questions

Word Knowledge
Cunning most nearly means:
crafty
Showing clever insight.
Math Knowledge
24

If a = c = 3, b = d = 8, and the blue angle = 58°, what is the area of this parallelogram?

24

The area of a parallelogram is equal to its length x width:

a = l x w
a = a x b
a = 3 x 8
a = 24

Word Knowledge
Accommodate most nearly means:
oblige
To give consideration to.
Arithmetic Reasoning

Which of the following is not an integer?

\({1 \over 2}\)

An integer is any whole number, including zero. An integer can be either positive or negative. Examples include -77, -1, 0, 55, 119.

Mechanical Comprehension

Specific gravity is a comparison of the density of an object with the density of:

water

Specific gravity is the ratio of the density of equal volumes of a substance and water and is measured by a hyrdometer.

Electronics Information
20 Ω Use Ohm's Law to calculate the value of resistance in this circuit if voltage is 40 volts and current is 2 amps.
20 Ω

Ohm's law specifies the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit: V = IR.

Solved for resistance, R = \( \frac{V}{I} \) = \( \frac{40}{2} \) = 20 Ω

Electronics Information

What is the primary difference between a rectifier and an inverter?

a rectifier converts an AC input to DC while an inverter converts a DC input to AC

A diode allows current to pass easily in one direction and blocks current in the other direction. Diodes are commonly used for rectification which is the conversion of alternating current (AC) into direct current (DC). Because a diode only allows current flow in one direction, it will pass either the upper or lower half of AC waves (half-wave rectification) creating pulsating DC. Multiple diodes can be connected together to utilize both halves of the AC signal in full-wave rectification.

Arithmetic Reasoning

This property states taht the order of addition or multiplication does not mater. For example, 2 + 5 and 5 + 2 are equivalent.

commutative

The commutative property states that, when adding or multiplying numbers, the order in which they're added or multiplied does not matter. For example, 3 + 4 and 4 + 3 give the same result, as do 3 x 4 and 4 x 3.

General Science

Which of the following is the smallest component of an element that still retains the properties of the element?

atom

An atom is the smallest component of an element that still retains the properties of the element.

Word Knowledge
Helen will only accept something of comparable value for her ticket to the concert.
akin
Similar, equivalent.
