Sample Practice Test Questions

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
20 Ω Use Ohm's Law to calculate the value of resistance in this circuit if voltage is 40 volts and current is 2 amps.
20 Ω

Ohm's law specifies the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit: V = IR.

Solved for resistance, R = \( \frac{V}{I} \) = \( \frac{40}{2} \) = 20 Ω

General Science

A transition zone between two air masses is called:

front

An air mass is a large body of air that has similar moisture (density) and temperature characteristics. A front is a transition zone between two air masses.

-40°F is how many °C?

-40

The formula to convert from F° to C° is:

\(C° = {5 \over 9} (F° - 32)\)

plugging in our values gives:

\(C° = {5 \over 9} (-40 - 32)\)

\(C° = {5 \over 9} (-72) = {{-72 \times 5} \over 9}\)

\(C° = {-360 \over 9}\)

\(C° = -40\)

Word Knowledge
The teacher made an exception and let Gina eat her snack in class.
anomaly
A case to which the rule does not apply.
Math Knowledge
\( \sqrt{80} \)

If side a = 8, side b = 4, what is the length of the hypotenuse of this right triangle?

\( \sqrt{80} \)

According to the Pythagorean theorem, the hypotenuse squared is equal to the sum of the two perpendicular sides squared:

c2 = a2 + b2
c2 = 82 + 42
c2 = 64 + 16
c2 = 80
c = \( \sqrt{80} \)

Math Knowledge

Solve for y:
y2 - 5y - 6 = 0

-1 or 6

The first step to solve a quadratic equation that's set to zero is to factor the quadratic equation:

y2 - 5y - 6 = 0
(y + 1)(y - 6) = 0

For this expression to be true, the left side of the expression must equal zero. Therefore, either (y + 1) or (y - 6) must equal zero:

If (y + 1) = 0, y must equal -1
If (y - 6) = 0, y must equal 6

So the solution is that y = -1 or 6

Electronics Information
AC source

This circuit component symbol represents a(n):

AC source

In contrast to the constant one-way flow of direct current, alternating current changes direction many times each second. Electricity is delivered from power stations to customers as AC because it provides a more efficient way to transport electricity over long distances.
