Sample Practice Test Questions

Electronics Information

Resistance and current are __________ proportional.

inversely

Resistance is opposition to the flow of current and is measured in ohms (Ω). One ohm is defined as the amount of resistance that will allow one ampere of current to flow if one volt of voltage is applied. As resistance increases, current decreases as resistance and current are inversely proportional.

Word Knowledge
Love–struck Charlie was oblivious to everyone but the object of his affection.
careless
Lacking awareness.
Word Knowledge
Gravity most nearly means:
seriousness
Importance, significance.
Automotive Information

Which of the following is not a function of a car battery?

acts as a supplemental source of energy to moderate engine performance

The lead-acid battery is the core of the electrical system, providing current to the ignition system to start the engine as well as delivering supplemental current when the alternator can't handle high electrical system loads and acting as an electrical reservoir for excessive current.

Mechanical Comprehension

A fixed pulley is useful for which of the following?

changing the direction of the input force

A fixed pulley is used to change the direction of a force and does not multiply the force applied. As such, it has a mechanical advantage of one. The benefit of a fixed pulley is that it can allow the force to be applied at a more convenient angle, for example, pulling downward or horizontally to lift an object instead of upward.

General Science

The universal recipient blood type can recieve any other blood type. Which blood type is the universal recipient?

AB-positive

Blood transfer is limited by the type and Rh factor of the blood. Someone who has Rh-factor negative blood cannot receive blood with a positive type but a person with Rh-factor positive type blood can receive Rh-negative blood. Type O negative blood is the universal donor because it can be given to a person with any blood type. Type AB positive is the universal recipient meaning someone with this blood type can receive any other type of blood.

Word Knowledge
Buffer most nearly means:
cushion
Protective barrier.
General Science

A human heart consists of how many chambers?

4

The heart is the organ that drives the circulatory system. In humans, it consists of four chambers with two that collect blood called atria and two that pump blood called ventricles. The heart's valves prevent blood pumped out of the ventricles from flowing back into the heart.

Mechanical Comprehension

Which of the following is not true of a  first-class lever?

decreases distance

A first-class lever is used to increase force or distance while changing the direction of the force. The lever pivots on a fulcrum and, when a force is applied to the lever at one side of the fulcrum, the other end moves in the opposite direction. The position of the fulcrum also defines the mechanical advantage of the lever. If the fulcrum is closer to the force being applied, the load can be moved a greater distance at the expense of requiring a greater input force. If the fulcrum is closer to the load, less force is required but the force must be applied over a longer distance. An example of a first-class lever is a seesaw / teeter-totter.

General Science

The gravitational interaction of Earth and the Moon is responsible for which of these?

tides

Tides are caused by the gravitational interaction of Earth and the Moon.
