Sample Practice Test Questions

Electronics Information

What is the voltage of most household electrical systems in the United States?

110V

Most households use electricity with a voltage of 110V.

Word Knowledge
Melodious most nearly means:
dulcet
Having a pleasing melody.
Word Knowledge
Even though I forgot his birthday, I hoe my father accepts my belated card.
tardy
Past the normal or proper time.
Electronics Information

Which of the following is the formula for calculating electrical power?

P = IV

Electrical power is measured in watts (W) and is calculated by multiplying the voltage (V) applied to a circuit by the resulting current (I) that flows in the circuit: P = IV. In addition to measuring production capacity, power also measures the rate of energy consumption and many loads are rated for their consumption capacity. For example, a 60W lightbulb utilizes 60W of energy to produce the equivalent of 60W of heat and light energy.

General Science

Velocity is the rate at which an object changes position. What is the formula for velocity? 

\(\vec{v} = { \vec{d} \over t } \)

Velocity is the rate at which an object changes position. Rate is measured in time and position is measured in displacement so the formula for velocity becomes  \(\vec{v} = { \vec{d} \over t } \) 

Automotive Information

__________ are made with wide gap coils of rigid steel cable and both hold the vehicle chassis up off the ground and absorb energy from wheel movement making for a smoother ride.

suspension springs

Suspension springs are made with wide gap coils of rigid steel cable and both hold the vehicle chassis up off the ground and absorb energy from wheel movement making for a smoother ride.

Word Knowledge
Obnoxious most nearly means:
objectionable
Highly offensive.
Math Knowledge

What is the circumference of a circle with a radius of 18?

36π

The formula for circumference is circle diameter x π. Circle diameter is 2 x radius:

c = πd
c = π(2 * r)
c = π(2 * 18)
c = 36π

Math Knowledge

Breaking apart a quadratic expression into a pair of binomials is called:

factoring

To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.

Math Knowledge

Solve for y:
-5y - 3 = \( \frac{y}{-3} \)

-\(\frac{9}{14}\)

To solve this equation, 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.

-5y - 3 = \( \frac{y}{-3} \)
-3 x (-5y - 3) = y
(-3 x -5y) + (-3 x -3) = y
15y + 9 = y
15y + 9 - y = 0
15y - y = -9
14y = -9
y = \( \frac{-9}{14} \)
y = -\(\frac{9}{14}\)
