Convert 5C° to F°.

53% Answer Correctly

37

-23

41

27


Solution

To convert from C° to F° use:

\(F° = {9 \over 5}C° + 32\)

\(F° = {9 \over 5}(5) + 32\)

\(F° = {45 \over 5} + 32\)

\(F° = 9 + 32 = 41\)


2

As part of the carbon cycle, plants release carbon into the atmosphere through which process?

45% Answer Correctly

photosynthesis

sedimentation

decomposition

evaporation


Solution

The carbon cycle represents the ciruit of carbon through Earth's ecosystem. Carbon dioxide (CO2) in the atmosphere is absorbed by plants through photosynthesis. Plants then die and release carbon back into the atmosphere during decomposition or are eaten by animals who breathe (respiration) the carbon into the atmosphere they exhale and produce waste which also releases carbon as it decays.


3

The brain and spinal cord make up the __________ nervous system.

81% Answer Correctly

central

somatic

peripheral

autonomic


Solution

The nervous system consists of the brain and spinal cord (central nervous system) and the peripheral nervous system which is the network of nerve cells (neurons) that collect and distribute signals from the central nervous system throughout the body.


4

Cirrus clouds generally occur in what kind of weather?

51% Answer Correctly

stormy

fair

hot

freezing


Solution

Cirrus clouds are thin, wispy high-altitude clouds composed of ice crystals that originate from the freezing of supercooled water droplets. Cirrus clouds generally occur in fair weather and point in the direction of air movement at their elevation.


5

Momentum is a measure of how difficult it is for a moving object to stop. Which of the following is the formula for momentum?

60% Answer Correctly

\(\vec{p} = m\vec{v}\)

\(\vec{p} = {m \over \vec{v}}\)

none of these

\(\vec{p} = { \vec{v} \over m}\)


Solution

Momentum is a measure of how difficult it is for a moving object to stop and is calculated by multiplying the object's mass by its velocity:  \(\vec{p} = m\vec{v}\).  Like velocity, momentum is a vector quantity as it expresses force applied in a specific direction.
