Q: Q: The oceans affect earth's atmosphere and influence its what? Read this paragraph and choose the correct option from the provided answers: Much of Earth's surface is covered with oceans. That's why Earth is called the "water planet. " Without all that water, Earth would be a very different place. The oceans affect Earth's atmosphere and influence its climate. An incredible diversity of living things inhabit the ocean as well. You might think that oceans have always covered Earth's surface, but you would be wrong!. Choices: - earthquakes - mountains - volcanoes - climate A:
A: climate

Q: Q: The entire range of light that can be seen by the human eye without aid is known as what kind of light? Read this paragraph and choose the correct option from the provided answers: Why is this picture of a cat so colorful? No cat looks like this to the human eye. The picture was taken with a special camera that senses infrared light. This is a form of energy given off by warm objects. Areas that appear yellow are the warmest, and areas that appear purple are the coolest. The picture shows that the cat's eyes are the warmest part of its head. Why can't people see images like this without a camera? The answer has to do with the wavelengths of infrared light. Its wavelengths are too long for the human eye to detect. In fact, the human eye can detect light only in a very narrow range of wavelengths, called visible light. You'll learn more about infrared light, visible light, and other forms of electromagnetic radiation in this chapter. Choices: - white light - colored light - infrared light - visible light A:
A: visible light

Q: Q: The great astronomer edwin hubble discovered that all distant galaxies are receding from our milky way galaxy with velocities proportional to their what? Read this paragraph and choose the correct option from the provided answers: (a) A jet airplane flying from Darwin, Australia, has an air speed of 260 m/s in a direction 5.0 south of west. It is in the jet stream, which is blowing at 35.0 m/s in a direction 15 south of east. What is the velocity of the airplane relative to the Earth? (b) Discuss whether your answers are consistent with your expectations for the effect of the wind on the plane's path. (a) In what direction would the ship in Exercise 3.57 have to travel in order to have a velocity straight north relative to the Earth, assuming its speed relative to the water remains 7.00 m/s ? (b) What would its speed be relative to the Earth? 60. (a) Another airplane is flying in a jet stream that is blowing at 45.0 m/s in a direction 20 south of east (as in Exercise 3.58). Its direction of motion relative to the Earth is 45.0 south of west, while its direction of travel relative to the air is 5.00 south of west. What is the airplane's speed relative to the air mass? (b) What is the airplane's speed relative to the Earth? 61. A sandal is dropped from the top of a 15.0-m-high mast on a ship moving at 1.75 m/s due south. Calculate the velocity of the sandal when it hits the deck of the ship: (a) relative to the ship and (b) relative to a stationary observer on shore. (c) Discuss how the answers give a consistent result for the position at which the sandal hits the deck. The velocity of the wind relative to the water is crucial to sailboats. Suppose a sailboat is in an ocean current that has a velocity of 2.20 m/s in a direction 30.0 east of north relative to the Earth. It encounters a wind that has a velocity of 4.50 m/s in a direction of 50.0 south of west relative to the Earth. What is the velocity of the wind relative to the water? 63. The great astronomer Edwin Hubble discovered that all distant galaxies are receding from our Milky Way Galaxy with velocities proportional to their distances. It appears to an observer on the Earth that we are at the center of an expanding universe. Figure 3.64 illustrates this for five galaxies... Choices: - masses - paths - dimensions - distances A:
A: distances

Q: Q: Sensory neurons transmit nerve impulses from sense organs and internal organs to the brain via the? Read this paragraph and choose the correct option from the provided answers: Sensory neurons transmit nerve impulses from sense organs and internal organs to the brain via the spinal cord. In other words, they carry information about the inside and outside environment to the brain. Choices: - nervous system - nerve endings - spinal column - spinal cord A:
A: spinal cord
