1

Generally, an atom has __________ negative electrons orbiting the nucleus as it does positive protons inside.

67% Answer Correctly

more

fewer

double the number of

equal numbers of


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.


2

What kind of weather front is likely to create clouds and storms?

58% Answer Correctly

temperate front

cold front 

warm front

stationary front


Solution

A warm front is the boundary between warm and cool (or cold) air when the warm air is replacing the cold air. Warm air at the surface pushes above the cool air mass creating clouds and storms.


3

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

64% Answer Correctly

G

E

D

S


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

A subatomic particle found in the nucleus of an atom. It carries a positive electric charge. This desribes which of the following?

80% Answer Correctly

atom

electron

neutron

proton


Solution

A proton is a subatomic particle found in the nucleus of an atom. It carries a positive electric charge.


5

A major difference between sound waves and light waves is which of the following?

70% Answer Correctly

a sound wave is much slower than a light wave

all of these are correct

a sound wave is mechanical while a light wave is electromagnetic

a sound wave cannot travel through a vacuum


Solution

A vibrating object produces a sound wave that travels outwardly from the object through a medium (any liquid or solid matter). The vibration disturbs the particles in the surrounding medium, those particles disturb the particules next to them, and so on, as the sound propagates away from the vibration.
