Convert 5C° to F°.

53% Answer Correctly

	41
	27
	-23
	37

Solution

To convert from C° to F° use:

\(F° = {9 \over 5}C° + 32\)

\(F° = {9 \over 5}(5) + 32\)

\(F° = {45 \over 5} + 32\)

\(F° = 9 + 32 = 41\)

Which of the following is not a vector quantity?

62% Answer Correctly

	mass
	velocity
	acceleration
	momentum

Solution

Velocity and displacement are vector quantities which means each is fully described by both a magnitude and a direction. In contrast, scalar quantities are quantities that are fully described by a magnitude only. A variable indicating a vector quantity will often be shown with an arrow symbol: \(\vec{v}\)

Gametes have how many pairs of chromosomes?

76% Answer Correctly

	23
	2
	4
	46

Solution

Reproductive (haploid) cells known as gametes have half as many (23) pairs of chromosomes as normal (diploid) cells. When the male gamete (sperm) combines with the female gamete (ovum) through meiosis to form a zygote, each gamete supplies half the chromosomes needed to form the normal diploid cells.

Which of the following is not true about simple magnets?

62% Answer Correctly

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

78% Answer Correctly

	decrease, stabilize
	decrease, raise
	stabilize, raise

Solution
