Vector quantities are fully described by which of the following?

75% Answer Correctly

	a direction only
	a direction and a polarity
	a magnitude and a direction
	a magnitude only

Solution

Velocity and displacement are vector quantities which means each is fully described by both a magnitude and a direction.

Convert 5C° to F°.

53% Answer Correctly

	-23
	37
	41
	27

Solution

To convert from C° to F° use:

\(F° = {9 \over 5}C° + 32\)

\(F° = {9 \over 5}(5) + 32\)

\(F° = {45 \over 5} + 32\)

\(F° = 9 + 32 = 41\)
