1

The energy posessed by a thrown baseball is an example of what kind of energy?

79% Answer Correctly

transitional

potential

gravitational

kinetic


Solution

Kinetic energy is the energy posessed by a moving object. Potential energy is stored energy in a stationary object based on its location, position, shape, or state.


2

Generally, an atom has __________ negative electrons orbiting the nucleus as it does positive protons inside.

67% Answer Correctly

equal numbers of

fewer

double the number of

more


Solution

An electron is a subatomic particle that orbits the nucleus of an atom. It carries a negative electric charge. Generally, an atom has the same number of negative electrons orbiting the nucleus as it does positive protons inside.


3

50°F is how many °C?

72% Answer Correctly

-10

122

58

10


Solution

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

\(C° = {5 \over 9} (F° - 32)\)

plugging in our values gives:

\(C° = {5 \over 9} (50 - 32)\)

\(C° = {5 \over 9} (18)\)

\(C° = {90 \over 9}\)

\(C° = 10\)


4

Vector quantities are fully described by which of the following?

75% Answer Correctly

a magnitude only

a direction and a polarity

a magnitude and a direction

a direction only


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:  \(\vec{v}\)


5

An element in the physical state of __________ maintains neither a constant volume nor a constant shape.

75% Answer Correctly

solid

plasma

liquid

gas


Solution

The gaseous state occurs at a higher temperature range than the solid and liquid states of the same substance. In this state, molecules flow very freely around each other and will spread out as far as they're able. Gases maintain neither a constant volume nor a constant shape.
