Answer the following question given this paragraph: If you've ever seen a kayak move down a fast-moving river, you know that remaining in the same place would be hard. The river current pulls the kayak along. Pushing the oars back against the water can move the kayak forward in the water, but that only accounts for part of the velocity. The kayak's motion is an example of classical addition of velocities. In classical physics, velocities add as vectors. The kayak's velocity is the vector sum of its velocity relative to the water and the water's velocity relative to the riverbank. Q: The kayak's motion in the water is an example of classical addition of what? Choices: - momentum - force - acceleration - velocities A:
velocities

Answer the following question given this paragraph: Unsaturated hydrocarbons that contain at least one double bond are called alkenes . The name of a specific alkene always ends in ene , with a prefix indicating the number of carbon atoms. Figure below shows the structural formula for the smallest alkene. It has just two carbon atoms and is named ethene. Ethene is produced by most fruits and vegetables. It speeds up ripening and also rotting. Figure below shows the effects of ethene on bananas. Q: What is the name for unsaturated hydrocarbons that contain at least one double bond? Choices: - lipids - acids - enzymes - alkenes A:
alkenes

Answer the following question given this paragraph: The oldest crust is coldest and lies deepest in the ocean. Q: Which crust lies deep inside the ocean? Choices: - shallowest - youngest - thickest - oldest A:
