50°F is how many °C?

72% Answer Correctly

	122
	10
	-10
	58

Solution

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

\(C° = {5 \over 9} (F° - 32)\)

plugging in our values gives:

\(C° = {5 \over 9} (50 - 32)\)

\(C° = {5 \over 9} (18)\)

\(C° = {90 \over 9}\)

\(C° = 10\)

Convert 0C° to F°.

72% Answer Correctly

	-32
	16
	32
	0

Solution

To convert from C° to F° use:

\(F° = {9 \over 5}C° + 32\)

\(F° = {9 \over 5}(0) + 32\)

\(F° = 0 + 32 = 32\)

Which of the following is not true about simple magnets?

62% Answer Correctly

	opposite poles attract each other
	all of these are untrue
	opposite poles repel each other
	same poles repel each other

Solution

Simple magnets have two poles, north and south, and opposite poles attract each other (N attracts S, S attracts N). Likewise, the same pole of two magnets repel (N repels N, S repels S). The Earth has a magnetic field and North and South Poles which enables the use of a magnetic compass to determine direction.

What type of cloud is responsible for fog?

62% Answer Correctly

	cumulus
	stratus
	cirrus
	cumulonimbus

Solution

Clouds are categorized based on their shape, size, and altitude. Stratus clouds are low-altitude clouds characterized by horizontal layering with a broad flat base. When stratus clouds occur on the ground the result is fog.
