(Q).
Answer the following question given this paragraph: In science, a law is a mathematical relationship that exists between observations under a given set of conditions. There is a fundamental difference between observations of the physical world and explanations of the nature of the physical world. Hypotheses and theories are explanations, whereas laws and measurements are observational. Q: In science, what do we call a mathematical relationship that exists between observations under a given set of conditions? Choices: - idea - theory - fact - law A:
(A).
law

Answer the following question given this paragraph: Q: What are the poles labeled? Choices: - west and south - southwest and south - east and west - north and south A:
(A).
north and south

(Q).
Answer the following question given this paragraph: Newton's second law shows that there is a direct relationship between force and acceleration. The greater the force that is applied to an object of a given mass, the more the object will accelerate. For example, doubling the force on the object doubles its acceleration. The relationship between mass and acceleration, on the other hand, is an inverse relationship. The greater the mass of an object, the less it will accelerate when a given force is applied. For example, doubling the mass of an object results in only half as much acceleration for the same amount of force. Q: Which of newton's law shows that there is a direct relationship between force and acceleration? Choices: - third - none of the above - first - second A:
(A).
second
