Sample Practice Test Questions

Math Knowledge

A(n) __________ is two expressions separated by an equal sign.

equation

An equation is two expressions separated by an equal sign. The key to solving equations is to repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.

General Science

Stratus clouds are __________clouds characterized by horizontal layering with a broad flat base. 

low-altitude

Clouds are categorized based on their shape, size, and altitude. Stratus clouds are low-altitude clouds characterized by horizontal layering with a broad flat base. When stratus clouds occur on the ground the result is fog.

Electronics Information

The volt is a unit of measurement for:

voltage

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.

General Science

Which of the following would you find in the side view mirror of a car?

convex mirror

A concave (or converging) mirror bulges inward and focuses reflected light on the mirror's focal point where the mirror's angles of incidence converge. In contrast, a convex (or diverging) mirror bulges outward and diffuses the light waves that strike it. A common use of a concave mirror is in a reflecting telescope, a common use of a convex mirror is in the side view mirror of a car.

Electronics Information

Which of the following converts electrical energy into another form of energy in an electrical circuit?

load

A load is a source of resistance that converts electrical energy into another form of energy. The components of a microwave, for example, are loads that work together to convert household electricity into radation that can be used to quickly cook food.

Electronics Information
resistor

This circuit component symbol represents a(n):

resistor

Resistors are used to limit voltage and/or current in a circuit and can have a fixed or variable resistance.  Variable resistors (often called potentiometers or rheostats) are used when dynamic control over the voltage/current in a circuit is needed, for example, in a light dimmer or volume control.

Automotive Information

What combines the suspension spring and shock absorber into one unit?

strut

Because a compressed spring will ex­tend violently, shock absorbers must be used to dampen the spring’s compression and extension cycles. Struts combine the spring and shock into one unit

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

The primary difference between a standard level and a bullseye level is which of the following?

a bullseye level can measure across two dimensions

Levels utlize a fluid-filled tube containing a bubble that is centered when the surface is horizontal (level) or vertical (plumb) along the direction of the tube. While a standard level can measure along a single dimension, a bullseye level is circular and can indicate the levelness of a two dimensional plane.

Shop Information

Measuring tools provide a convenient and easy way to compare object dimensions against:

a standard

Measuring tools give easy access to the wide variety of standard dimensions that are used to categorize and classify objects.
