The Earth's rocks fall into three categories based on how they're formed. Which of the following is formed from the hardening of molten rock?
igneous
The Earth's rocks fall into three categories based on how they're formed. Igneous rock (granite, basalt, obsidian) is formed from the hardening of molten rock (lava), sedimentary rock (shale, sandstone, coal) is formed by the gradual despositing and cementing of rock and other debris, and metamorphic rock (marble, slate, quartzite) which is formed when existing rock is altered though pressure, temperature, or chemical processes.
Which types of triangles will always have at least two sides of equal length?
equilateral and isosceles
An isosceles triangle has two sides of equal length. An equilateral triangle has three sides of equal length. In a right triangle, two sides meet at a right angle.
Two or more pulleys used together are called:
block and tackle
Two or more pulleys used together constitute a block and tackle which, unlike a fixed pulley, does impart mechanical advantage as a function of the number of pulleys that make up the arrangement. So, for example, a block and tackle with three pulleys would have a mechanical advantage of three.
Which engine component converts the reciprocating motion of the piston into the rotational motion that's used to power the vehicle and its components?
crankshaft
The crankshaft converts the reciprocating motion of the piston into the rotational motion that's used to power the vehicle and its components.
Which of the following is not a function of a car battery?
acts as a supplemental source of energy to moderate engine performance
The lead-acid battery is the core of the electrical system, providing current to the ignition system to start the engine as well as delivering supplemental current when the alternator can't handle high electrical system loads and acting as an electrical reservoir for excessive current.
Which of the following is not true about a line drop?
it is addressed by raising current and lowering voltage across the ransmission line
Electricity is delivered from power stations to customers as AC because it provides a more efficient way to transport electricity over long distances. A line drop is a decrease in voltage between two points on an electrical transmission line due to resistance in the line. A lower current and higher voltage across the line will help compensate for the line drop.
When cutting hard metals with a hacksaw you should choose a blade with __________ teeth per inch (TPI).
high
Blades with more and smaller teeth (high TPI) cut harder metals more effectively while blades with fewer and larger teeth (low TPI) cut softer metals more effectively.
Which of the following is not a base unit in the metric system?
degree Fahrenheit
The Fahrenheit scale is used for measuring temperature in the British system. The metric system uses the Celsius scale.
As part of digestion, the liver produces bile which breaks down:
fat
The liver produces bile which emulsifies (separates) fat.
