Sample Practice Test Questions
The dimensions of this cylinder are height (h) = 5 and radius (r) = 4. What is the surface area?
The surface area of a cylinder is 2πr2 + 2πrh:
sa = 2πr2 + 2πrh
sa = 2π(42) + 2π(4 x 5)
sa = 2π(16) + 2π(20)
sa = (2 x 16)π + (2 x 20)π
sa = 32π + 40π
sa = 72π
How are the cylinders numbered in V-type engines?
cylinder numbering varies by manufacturer
In V-type engines the numbering sequence varies by manufacturer.
Tertiary consumers eat which of the following?
primary and secondary consumers
Tertiary consumers eat primary consumers and secondary consumers and are typically carnivorous predators. Tertiary consumers may also be omnivores. Examples include wolves, sharks, and human beings.
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.
What is a caliper used for?
transferring distances between objects
Calipers are similar to micrometers in shape but instead of measuring distances, calipers are used to transfer distances between objects. An outside caliper is used to transfer outside dimensions while an inside caliper is used to transfer inside distances. A vernier caliper is an extremely precise caliper (down to \({1 \over 1000}\) inch) that allows measuring / transferring either inside or outside dimensions.
The valence shell of a conductor is how full of electrons?
less than half full
Conductors are elements that allow electrons to flow freely. Their valence shell is less than half full of electrons that are able to move easily from one atom to another.
Which of the following allows encapsulating complex circuit designs for easier integration into electronic devices and machines?
integrated circuits
Circuits containing transistors are packaged into integrated circuit chips that allow encapsulating complex circuit designs (CPU, memory, I/O) for easier integration into electronic devices and machines.
Which of the following statements about electrical resistance is true?
the more resistive the conductor is the slower electron flow will be
Resistance is opposition to the flow of current. As resistance increases, current decreases as resistance and current are inversely proportional.
