Large, puffy, mid-altitude clouds with a flat base and a rounded top describe which of the following?
stratus clouds |
|
cirrus clouds |
|
fog |
|
cumulus clouds |
Cumulus clouds are large, puffy, mid-altitude clouds with a flat base and a rounded top. These clouds grow upward and can develop into a cumulonimbus or thunderstorm cloud.

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.
What type of cloud is responsible for fog?
cumulus |
|
cirrus |
|
cumulonimbus |
|
stratus |
Clouds are categorized based on their shape, size, and altitude. Stratus clouds are low-altitude clouds characterized by horizontal layering with a broad flat base. When stratus clouds occur on the ground the result is fog.
During digestion, after proteins are broken down where does the undigested food go next?
large intestine |
|
stomach |
|
esophagus |
|
small intestine |
Food is mixed with gastric acid and pepsin in the stomach to help break down protein.
"The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object." This describes which of Newton's laws of motion?
second |
|
first |
|
fourth |
|
third |
Newton's second law of motion states that The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. This law basically means that the greater the mass of an object, the more force is needed to overcome its inertia.
