1

Which of the following is not a vector quantity?

62% Answer Correctly

mass

momentum

acceleration

velocity


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:  \(\vec{v}\)


2

A large naturally occurring community of flora and fauna occupying a major habitat is:

76% Answer Correctly

a food chain

a population

a community

a biome


Solution

A biome is a large naturally occurring community of flora (plants) and fauna (animals) occupying a major habitat (home or environment).


3

Plant cells are surrounded by:

63% Answer Correctly

only a cell membrane

only a cell wall

a cell membrane and a cell wall

neither a cell membrane nor a cell wall


Solution

Animal cells are surrounded by a semipermeable membrane which allows for the transfer of water and oxygen to and from the cell. In plant cells, the cell membrane is surrounded by a somewhat rigid cell wall which provides the cell structure and support.


4

212°F is how many °C?

78% Answer Correctly

-100

\(135 {5 \over 9}\)

100

0


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

Work is measured in:

75% Answer Correctly

amps

joules or newton-meters

horsepower

watts


Solution

Work is performed on an object when an applied force causes displacement along the same vector. Measured in joules (J) or newton-meters (Nm), work is calculated by multiplying force times displacement:  \(W = \vec{F}\vec{d}\)
