Answer the following question given this paragraph: A white dwarf is a stellar remnant that is very dense. A white dwarf's mass is comparable to the Sun and its volume is comparable to that of Earth. The very low brightness of a white dwarf comes from the emission of stored heat energy. Q: What is a stellar remnant that is very dense? Choices: - asteroids - the sun - white star - white dwarf A:
white dwarf

Answer the following question given this paragraph: Q: What three things do animals require in order to survive? Choices: - Sex, Love, Food - Shelter, Food and love - Immunity, blood, water - air, water, food A:
(Answer)
air, water, food
Ques: Answer the following question given this paragraph: Earthquake magnitude affects how much damage is done in an earthquake. A larger earthquake damages more buildings and kills more people than a smaller earthquake. But that's not the only factor that determines earthquake damage. The location of an earthquake relative to a large city is important. More damage is done if the ground shakes for a long time. Q: What general property of an earthquake is used to describe its relative strength? Choices: - resonance - latitude - amplitude - magnitude A:
Ans: magnitude
(Q).
Answer the following question given this paragraph: Food calories are determined by burning the food and measuring the heat released. Q: What property of food is determined by burning the food and measuring the heat released? Choices: - acidity - nutrients - additives - calories A:
(A).
calories
Ques:Answer the following question given this paragraph: Introduction to Oscillatory Motion and Waves What do an ocean buoy, a child in a swing, the cone inside a speaker, a guitar, atoms in a crystal, the motion of chest cavities, and the beating of hearts all have in common? They all oscillate-that is, they move back and forth between two points. Many systems oscillate, and they have certain characteristics in common. All oscillations involve force and energy. You push a child in a swing to get the motion started. The energy of atoms vibrating in a crystal can be increased with heat. You put energy into a guitar string when you pluck it. Some oscillations create waves. A guitar creates sound waves. You can make water waves in a swimming pool by slapping the water with your hand. You can no doubt think of other types of waves. Some, such as water waves, are visible. Some, such as sound waves, are not. But every wave is a disturbance that moves from its source and carries energy. Other examples of waves include earthquakes and visible light. Even subatomic particles, such as electrons, can behave like waves. By studying oscillatory motion and waves, we shall find that a small number of underlying principles describe all of them and that wave phenomena are more common than you have ever imagined. We begin by studying the type of force that underlies the simplest oscillations and waves. We will then expand our exploration of oscillatory motion and waves to include concepts such as simple harmonic motion, uniform circular motion, and damped harmonic motion. Finally, we will explore what happens when two or more waves share the same space, in the phenomena known as superposition and interference. Q: Earthquakes and visible light are examples of what? Choices: - geological phenomena - currents - winds - waves A:

Ans:waves
