Sample Practice Test Questions

General Science

Cirrus clouds are thin, wispy clouds composed of ice crystals. At what elevation to cirrus clouds form?

high-altitude

Cirrus clouds are thin, wispy high-altitude clouds composed of ice crystals that originate from the freezing of supercooled water droplets. Cirrus clouds generally occur in fair weather and point in the direction of air movement at their elevation.

Electronics Information

What is the potential difference in an electrical circuit a measure of?

the voltage at a specific location in the circuit

Electrons flow from an area of high concentration to an area of low concentration. A high voltage indicates a high concentration of electrons that creates a greater potential for electron flow than a low voltage. When applied to a load, voltage creates electricity and potential difference is the measure of voltage at a specific location in an electrical circuit.

Word Knowledge
Retroactive most nearly means:
retrograde
effective as of a prior time or condition.
Electronics Information

A diode to an electronic circuit is like a _______________ to a city?

one-way street

A diode allows current to pass easily in one direction and blocks current in the other direction.

Word Knowledge

repulse
To resist, reject.
Word Knowledge
Absolve most nearly means:
exculpate
To forgive; to free from guilt.
General Science

Veins __________ blood at __________ pressure.

deoxygenated, low

Veins carry blood back to the heart from the body. While arteries are thick-walled because they carry oxygenated blood at high pressure, veins are comparatively thin-walled as they carry low-pressure deoxygenated blood. Like the heart, veins contain valves to prevent blood backflow.

Mechanical Comprehension

Which of the following statements about drag is false?

slower objects experience more drag than faster objects

Drag is friction that opposes movement through a fluid like liquid or air. The amount of drag depends on the shape and speed of the object with slower objects experiencing less drag than faster objects and more aerodynamic objects experiencing less drag than those with a large leading surface area.

General Science

An asteroid belt holds many of the asteroids in our solar system. It is located between the orbits of which planets?

Mars and Jupiter

The solar system also contains over a million rocky fragments of at least 1km in diameter called asteroids as well as millions more with smaller diameters. Many of these asteroids are an asteroid belt between the orbits of Mars and Jupiter.

Word Knowledge
The longer Jorge waited in line at the ticket counter, the more his exasperation grew.
irritation
The state of being irritated.
