1

50°F is how many °C?

72% Answer Correctly

-10

58

122

10


Solution

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

\(C° = {5 \over 9} (F° - 32)\)

plugging in our values gives:

\(C° = {5 \over 9} (50 - 32)\)

\(C° = {5 \over 9} (18)\)

\(C° = {90 \over 9}\)

\(C° = 10\)


2

An asteroid belt holds many of the asteroids in our solar system. It is located between the orbits of which planets?

59% Answer Correctly

Mercury and Venus

Jupiter and Saturn

Mars and Earth

Mars and Jupiter


Solution

The solar system also contains over a million rocky fragments of at least 1km in diameter called asteroids as well as millions more with smaller diameters. Many of these asteroids are an asteroid belt between the orbits of Mars and Jupiter.


3

A subatomic particle that orbits the nucleus of an atom. It carries a negative electric charge. This desribes which of the following?

74% Answer Correctly

electron

neutron

isotope

proton


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.


4

The heart __________ blood.

61% Answer Correctly

deoxygenates

oxygenates

creates

filters


Solution

To provide oxygen to the body, blood flows through the heart in a path formed by the right atrium → right ventricle → lungs → left atrium → left ventricle → body. When blood enters the right side of the heart it is deoxygenated. It enters the left side of the heart oxygenated after traveling to the lungs.


5

Which of the following would be used in eye glasses to correct farsightedness?

64% Answer Correctly

convex lens

concave lens

concave mirror

convex mirror


Solution

Unlike curved mirrors that operate on the principle of reflection, lenses utilize refraction. A convex lens is thicker in the middle than on the edges and converges light while a concave lens is thicker on the edges than in the middle and diffuses light. A common use for curved lenses is in eye glasses where a convex lens is used to correct farsightedness and a concave lens is used to correct nearsightedness.
