1

Convert 0C° to F°.

72% Answer Correctly

0

-32

16

32


Solution

To convert from C° to F° use:

\(F° = {9 \over 5}C° + 32\)

\(F° = {9 \over 5}(0) + 32\)

\(F° = 0 + 32 = 32\)

 


2

Which of blood component allows blood to clot?

74% Answer Correctly

red blood cells

white blood cells

plasma

platelets


Solution

Blood is created in bone marrow and is made up of cells suspended in liquid plasma. Red blood cells carry oxygen, white blood cells fight infection, and platelets are cell fragments that allow blood to clot.


3

Which of the following is metamorphic rock?

52% Answer Correctly

obsidian

marble

granite

coal


Solution

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.


4

212°F is how many °C?

77% Answer Correctly

0

\(135 {5 \over 9}\)

-100

100


Solution

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

\(C° = {5 \over 9} (F° - 32)\)

plugging in our values gives:

\(C° = {5 \over 9} (212 - 32)\)

\(C° = {5 \over 9} (180) = {{180 \times 5} \over 9}\)

\(C° = {900 \over 9}\)

\(C° = 100\)


5

Which of the following is not true of light waves?

62% Answer Correctly

travel faster than sound waves

are mechanical waves

are electromagnetic waves

can travel through a vacuum


Solution

Unlike mechanical sound waves that require a physical medium for propagation, light waves are electromagnetic and can travel through empty space. Light waves are also much faster, travelling at 186,000 m/s vs. 343 m/s for sound waves.
