Q: What unit of measurement determines how far something travels in a given amount of time? Read this paragraph and choose the correct option from the provided answers: How fast or slow something moves is its speed . Speed determines how far something travels in a given amount of time. The SI unit for speed is meters per second (m/s). Speed may be constant, but often it varies from moment to moment. Choices: - distance - volume - density - speed A:
speed

Q: Heat, electricity, or light might provide what necessary input to the process of decomposition? Read this paragraph and choose the correct option from the provided answers: Most decomposition reactions require an input of energy in the form of heat, light, or electricity. Choices: - source - material - food - energy A:
(Answer)
energy

Ques: Q: Amplitude describes what about the wave's crest and trough? Read this paragraph and choose the correct option from the provided answers: Waves are identified by several characteristics. There is a center line where the medium would be if there were no wave, which is sometimes describes as the undisturbed position. The displacement of the medium above this undisturbed position is called a crest and the displacement below the undisturbed position is called a trough . The maximums of the crest and trough are equal and are called the amplitude . The distance between equivalent positions on succeeding waves is called the wavelength . The wavelength could be measured from a crest to the next crest or from a trough to the next trough, and is commonly represented with the Greek letter lambda, . Choices: - The minimum parts - How frequently the parts occur - The width of the parts - the maximum parts A:
Ans: the maximum parts

Q: Canoe paddles, nutcracker, and hammer are examples of what type of simple machine? Read this paragraph and choose the correct option from the provided answers: The canoe paddles, nutcracker, and hammer that you read about in this lesson have something in common. All three are examples of a type of simple machine called a lever. Choices: - lock - handle - pivot - lever A:

Ques:Q: Physical science is defined as the study of what? Read this paragraph and choose the correct option from the provided answers: Look at the topographic map of Stowe, Vermont ( Figure below ). There is a steep hill rising just to the right of the city of Stowe. You can tell this because the contour lines there are closely spaced. The contour lines also show that the hill has a sharp rise of about 200 feet. Then the slope becomes less steep toward the right. Choices: - light & matter - biology & light - matter & elements - matter & energy A:

Ans:matter & energy

Ques: Q: In what energy industry process are fluids pumped through a borehole, creating fractures in the rock that contains the natural gas? Read this paragraph and choose the correct option from the provided answers: With fracking, fluids are pumped through a borehole. The fluids create fractures in the rock that contains the natural gas. Chemicals in the fluid prevent the fractures from closing. The natural gas can then be pumped to the surface. Choices: - grinding - oil wells - strip mining - fracking A:
Ans:
fracking
