Sample Practice Test Questions

Automotive Information

The catalytic converter output consists primarily of:

water and carbon dioxide

The catalytic converter converts pollutants in exhaust gas into less pollutant substances like carbon dioxide and water.

Electronics Information

Which of the following is the same for each branch of a parallel circuit?

voltage

In a parallel circuit, each load occupies a separate parallel path in the circuit and the input voltage is fully applied to each path. Unlike a series circuit where current (I) is the same at all points in the circuit, in a parallel circuit, voltage (V) is the same across each parallel branch of the circuit but current differs in each branch depending on the load (resistance) present.

Word Knowledge
Condone most nearly means:
excuse
To treat as acceptable.
Math Knowledge

What is the area of a circle with a radius of 2?

4π

The formula for area is πr2:

a = πr2
a = π(22)
a = 4π

Word Knowledge
Kim, an eloquent speaker, was the best choice to make the presentation for the group.
articulate
Fluent, expressive.
Word Knowledge
The rancorous competition between the two chess clubs actually ended in a brawl.
bitter
Marked by deep ill–will.
Mechanical Comprehension

A watt is the unit for which of the following?

power

Power is the rate at which work is done, P = w/t, or work per unit time. The watt (W) is the unit for power and is equal to 1 joule (or newton-meter) per second. Horsepower (hp) is another familiar unit of power used primarily for rating internal combustion engines. 1 hp equals 746 watts.

Word Knowledge
Authoritarian most nearly means:
strict
Favoring absolute obedience to authority.
Mechanical Comprehension

The force exerted on an object due to gravity is called:

weight

Mass is an intrinsic property of matter and does not vary. Weight is the force exerted on the mass of an object due to gravity and a specific case of Newton's Second Law of Motion. Replace force with weight and acceleration with acceleration due to gravity on Earth (g) and the result is the formula for weight: W = mg or, substituting for g, weight equals mass multiplied by 9.8 m/s2.

Word Knowledge
Sheila, who could not resist bragging, flaunted the "A" marked on her test paper.
parade
To display showily.
