Sample Practice Test Questions

Math Knowledge

Solve 3c + 2c = 9c - 9y + 8 for c in terms of y.

1\(\frac{5}{6}\)y - 1\(\frac{1}{3}\)

To solve this equation, isolate the variable for which you are solving (c) on one side of the equation and put everything else on the other side.

3c + 2y = 9c - 9y + 8
3c = 9c - 9y + 8 - 2y
3c - 9c = -9y + 8 - 2y
-6c = -11y + 8
c = \( \frac{-11y + 8}{-6} \)
c = \( \frac{-11y}{-6} \) + \( \frac{8}{-6} \)
c = 1\(\frac{5}{6}\)y - 1\(\frac{1}{3}\)

Word Knowledge

Which of the following is not an advantage of using a ratchet with a larger point-sized socket?

larger point sizes allow easier alignment

A ratchet (or socket wrench) is a wrench that applies torque in only one direction with a handle that can be moved back and forth without losing contact with the fastener. A ratchet uses variable attachments called sockets which come in a variety of drive sizes based on the size of the opening that attaches to the ratchet. Sockets with the same drive size will vary in the shape (six-point, twelve-point) and size of the nut opening that attaches to the fastener being tightened or loosened. Smaller point sized sockets are stronger and can apply greater torque while larger point sizes allow easier alignment.

Word Knowledge
Mandate most nearly means:
command
An official order or commission to do something.
Electronics Information
parallel circuit

This circuit diagram represents a(n):

parallel circuit

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
The executive was fired for his flagrant abuse of the company expense account.
glaring
Noticeably offensive.
General Science

Which of blood component allows blood to clot?

platelets

Blood is created in bone marrow and is made up of cells suspended in liquid plasma. Red blood cells carry oxygen, white blood cells fight infection, and platelets are cell fragments that allow blood to clot.

General Science

Vector quantities are fully described by which of the following?

a magnitude and a direction

Velocity and displacement are vector quantities which means each is fully described by both a magnitude and a direction.  In contrast, scalar quantities are quantities that are fully described by a magnitude only.  A variable indicating a vector quantity will often be shown with an arrow symbol:  \(\vec{v}\)

General Science

The energy posessed by a thrown baseball is an example of what kind of energy?

kinetic

Kinetic energy is the energy posessed by a moving object. Potential energy is stored energy in a stationary object based on its location, position, shape, or state.

Electronics Information

Direct current flows from the __________ terminal of the voltage source to the __________ terminal.

negative, positive

Direct current flows in only one direction in a circuit, from the negative terminal of the voltage source to the positive. A common source of direct current (DC) is a battery.
