1

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

79% Answer Correctly

gravitational

kinetic

potential

transitional


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

212°F is how many °C?

78% Answer Correctly

100

-100

0

\(135 {5 \over 9}\)


Solution

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

\(C° = {5 \over 9} (F° - 32)\)

plugging in our values gives:

\(C° = {5 \over 9} (212 - 32)\)

\(C° = {5 \over 9} (180) = {{180 \times 5} \over 9}\)

\(C° = {900 \over 9}\)

\(C° = 100\)

As a cold front moves into an area, the heavier cool air __________ the lighter warm air that it is replacing.

66% Answer Correctly

pushes under

mixes with

cancels out

pushes above


Solution

A cold front is a warm-cold air boundary with the colder air replacing the warmer. As a cold front moves into an area, the heavier cool air pushes under the lighter warm air that it is replacing. The warm air becomes cooler as it rises and, if the rising air is humid enough, the water vapor it contains will condense into clouds and precipitation may fall.


4

The crust and lithosphere of the Earth is made up of which of the following?

59% Answer Correctly

sedimentary rock

continents

plates

metamorphic rock


Solution

The crust and the rigid lithosphere (upper mantle) is made up approximately thirty separate plates. These plates more very slowly on the slightly more liquid mantle (asthenosphere) beneath them. This movement has resulted in continental drift which is the gradual movement of land masses across Earth's surface. Continental drift is a very slow process, occurring over hundreds of millions of years.


5

An electrically charged atom is a(n):

49% Answer Correctly

neutron

proton

electron

ion


Solution

A compound is a substance containing two or more different chemical elements bound together by a chemical bond. In ionic compounds, one atom borrows an electron from another atom resulting in two ions (electrically charged atoms) of opposite polarities that then become bonded electrostatically.
