1

212°F is how many °C?

77% Answer Correctly

0

-100

\(135 {5 \over 9}\)

100


Solution

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

\(C° = {5 \over 9} (F° - 32)\)

plugging in our values gives:

\(C° = {5 \over 9} (212 - 32)\)

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

\(C° = {900 \over 9}\)

\(C° = 100\)


2

Work is measured in:

75% Answer Correctly

watts

amps

horsepower

joules or newton-meters


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:  \(W = \vec{F}\vec{d}\)


3

Which of the following is not a characteristic of the Sun?

52% Answer Correctly

is a yellow dwarf star

makes up over 99% of the mass of the solar system

is composed of hydrogen and helium

formed 2.6 billion years ago


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.


4

The respiratory and circulatory systems are similar in that they:

84% Answer Correctly

deoxygenate blood

transport nutrients

add carbon dioxide

transport oxygen


Solution

Like the respiratory system, the circulatory system serves to transport oxygen throughout the body while removing carbon dioxide. In addition, the circulatory system transports nutrients from the digestive system.


5

The large intestine does which of the following?

82% Answer Correctly

breaks down starches

breaks down proteins

breaks down fats

processes the physical waste produced by digestion


Solution

The large intestine (colon) follows the small intestine and processes the physical waste produced by digestion, absorbing water and minerials that remain back into the body. Solid waste is then stored in the rectum while liquid waste is stored in the bladder.
