Convert 0C° to F°.

72% Answer Correctly

0

32

-32

16


Solution

To convert from C° to F° use:

\(F° = {9 \over 5}C° + 32\)

\(F° = {9 \over 5}(0) + 32\)

\(F° = 0 + 32 = 32\)

 


2

What part of the brain is responsible for the major senses (thinking, hearing, seeing)?

65% Answer Correctly

medulla

cerebrum

cerebellum

brainstem


Solution

The cerebrum is the major part of the brain and is responsible for the main senses (thinking, hearing, seeing).


3

Which of the following describes the Earth's mantle?

81% Answer Correctly

hot

makes up most of Earth's volume

all of these

dense


Solution

Mantle makes up 84% of the Earth's volume and has an average thickness of approximately 1,800 miles (2,900 km). It is dense, hot, and primarily solid although in places it behaves more like a viscous fluid as the plates of the upper mantle and crust gradually "float" along its circumference.


4

The Sun is a __________-type main-sequence star.

64% Answer Correctly

E

D

S

G


Solution

The Sun is a G-type main-sequence star (G2V) but is informally known as a yellow dwarf star. Composed of 73% hydrogen and 25% helium, the hot plasma that makes up the Sun reaches 9,900°F (5,505°C) at the surface. It formed approximately 4.6 billion years ago and makes up 99.86% of the mass in the solar system.


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

none of these

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

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

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


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.
