Answer the following question given this paragraph: When an action and reaction occur, momentum is transferred from one object to the other. However, the combined momentum of the objects remains the same. In other words, momentum is conserved. This is the law of conservation of momentum . Q: When an action and reaction occur, what is transferred from one object to the other, yet in combination it remains the same? Choices: - matter - force - energy - momentum A:
momentum
Answer the following question given this paragraph: The Earth is tilted on its axis ( Figure above ). This means that as the Earth rotates, one hemisphere has longer days with shorter nights. At the same time the other hemisphere has shorter days and longer nights. For example, in the Northern hemisphere summer begins on June 21. On this date, the North Pole is pointed directly toward the Sun. This is the longest day and shortest night of the year in the Northern Hemisphere. The South Pole is pointed away from the Sun. This means that the Southern Hemisphere experiences its longest night and shortest day ( Figure below ). Q: The earth is tilted on its what? Choices: - top - compass - radius - axis A:
axis
Q: Answer the following question given this paragraph: Note that Earth's axis of rotation is tilted. The axis is not perpendicular to the plane of the ecliptic. This plane is the one that solar system bodies are mostly lined up in. Q: What scale measures acidity? Choices: - frequency scale - richter scale - salinity scale - ph scale A:
A: ph scale
Question: Answer the following question given this paragraph: Arteries are muscular blood vessels that carry blood away from the heart. They have thick walls that can withstand the pressure of blood pumped by the heart. Arteries generally carry oxygen-rich blood. The largest artery is the aorta, which receives blood directly from the heart. It branches to form smaller and smaller arteries throughout the body. The smallest arteries are called arterioles. Q: What is the name of muscular blood vessels that carry blood away from the heart? Choices: - tubes - Veins - Aorta - arteries A:
Answer: arteries
