Answer the following question given this paragraph: Some of the damage done by storms is from storm surge . Low pressure in a storm pulls water upward. Water piles up at a shoreline as storm winds push waves into the coast. Storm surge may raise sea level as much as 7.5 m (25 ft). This can be devastating in a shallow land area when winds, waves, and rain are intense. Q: What weather phenomenon can raise sea level as much as 25 feet when low pressure pulls water upward? Choices: - earthquake surge - cloud formation - storm rise - storm surge A:
storm surge

Answer the following question given this paragraph: - For lenses, the distance from the center of the lens to the focus is . Focal lengths are positive for converging lens and negative for diverging lens. The distance from the center of the lens to the object in question is , where distances to the left of the lens are positive in sign. The distance from the center of the lens to the image is . This number is positive for real images (formed to the right of the lens), and negative for virtual images (formed to the left of the lens). Q: What lengths are positive for converging lens and negative for diverging lens? Choices: - light lengths - wavelengths - differential lengths - focal lengths A:
focal lengths

Answer the following question given this paragraph: Density is defined as the mass of an object divided by its volume. Propose a unit of density in terms of the fundamental SI units. Q: Density is defined as the mass of an object divided by its what? Choices: - size - liquid - growth - volume A:
volume

Answer the following question given this paragraph: Flowering vascular plants also have diverse leaves. However, the leaves of all flowering plants have two basic parts in common: the blade and petiole. The blade of the leaf is the relatively wide, flat part of the leaf that gathers sunlight and undergoes photosynthesis. The petiole is the part that attaches the leaf to a stem of the plant. This occurs at a node. Q: What are the two basic parts that all flowering plants have in common? Choices: - metal and petiole - stalk and petiole - leaf and petiole - blade and petiole A:
blade and petiole
