Sample Practice Test Questions
The fuel injectors are fed fuel by the:
electric fuel pump
The electric fuel pump feeds pressurized fuel through a fuel filter to the fuel injectors via the fuel rail manifold. The fuel rail contains the fuel pressure regulator which ensures that the fuel injectors receive fuel at a consistent and known rate. Excess fuel bled off by the pressure regulator returns to the fuel tank through the fuel return line.
Measuring tools provide a convenient and easy way to compare object dimensions against:
a standard
Measuring tools give easy access to the wide variety of standard dimensions that are used to categorize and classify objects.
This problem describes an inclined plane and, for an inclined plane, the effort force multiplied by the effort distance equals the resistance force multipied by the resistance distance:
Fede = Frdr
Plugging in the variables from this problem yields:
Fe x 14 ft. = 290 lbs. x 2 ft.
Fe = \( \frac{580 ft⋅lb}{14 ft.} \) = 41.4 lbs.
Power is the rate at which:
work is done
Power is the rate at which work is done, P = w/t, or work per unit time. The watt (W) is the unit for power and is equal to 1 joule (or newton-meter) per second. Horsepower (hp) is another familiar unit of power used primarily for rating internal combustion engines. 1 hp equals 746 watts.
Which of the following is the narrowest classification of life?
species
The narrowest classification of life, species, contains organisms that are so similar that they can only reproduce with others of the same species.
If side x = 12cm, side y = 9cm, and side z = 9cm what is the perimeter of this triangle?
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 12cm + 9cm + 9cm = 30cm
The __________ converts pressure on the brake pedal to hydraulic pressure in the brake lines.
master cylinder
The master (brake) cylinder converts pressure on the brake pedal to hydraulic pressure in the brake lines.
Which of the following substances gives up positively charged hydrogen ions (H+) when dissolved in water?
acid
An acid is a substance that gives up positively charged hydrogen ions (H+) when dissolved in water. A base (alkaline) gives up negatively charged hydroxide ions (OH-) when dissolved in water. pH is a scale that measures of how basic or acidic a solution is. Numbered from 0 to 14, solutions with a pH of 7 are neutral, less than 7 are acidic, more than 7 are alkaline.
