Answer the following question given this paragraph: Energy that the sun and other stars release into space is called electromagnetic energy . This form of energy travels through space as electrical and magnetic waves. Electromagnetic energy is commonly called light. It includes visible light, as well as radio waves, microwaves, and X rays ( Figure below ). Q: Energy that the sun and other stars release into space is called what? Choices: - static energy - kinetic energy - mechanical energy - electromagnetic energy A:
electromagnetic energy

Answer the following question given this paragraph: We already know that visible light is the type of electromagnetic waves to which our eyes respond. That knowledge still leaves many questions regarding the nature of light and vision. What is color, and how do our eyes detect it? Why do diamonds sparkle? How does light travel? How do lenses and mirrors form images? These are but a few of the questions that are answered by the study of optics. Optics is the branch of physics that deals with the behavior of visible light and other electromagnetic waves. In particular, optics is concerned with the generation and propagation of light and its interaction with matter. What we have already learned about the generation of light in our study of heat transfer by radiation will be expanded upon in later topics, especially those on atomic physics. Now, we will concentrate on the propagation of light and its interaction with matter. It is convenient to divide optics into two major parts based on the size of objects that light encounters. When light interacts with an object that is several times as large as the light's wavelength, its observable behavior is like that of a ray; it does not prominently display its wave characteristics. We call this part of optics "geometric optics. " This chapter will concentrate on such situations. When light interacts with smaller objects, it has very prominent wave characteristics, such as constructive and destructive interference. Wave Optics will concentrate on such situations. Q: What type of physics explains the behavior of visible light and electromagnetic waves? Choices: - Quantum mechanics - Thermodynamics - statistics - optics A:
(Answer)
optics
Ques: Answer the following question given this paragraph: A type of lipid called trans fat is found in many processed foods. Trans fat is rare in nature but is manufactured and added to foods to preserve freshness. Eating foods that contain trans fat increases the risk of heart disease. Trans fat may be found in such foods as cookies, doughnuts, crackers, fried foods, ground beef, and margarine. Q: What is manufactured and added to foods to preserve freshness? Choices: - carbohydrates - vitamin c - protein - trans fat A:
Ans: trans fat

Answer the following question given this paragraph: The distance between the Earth and the Sun is about 93 million miles, or 150 million kilometers. Earth revolves around the Sun at an average speed of about 27 kilometers (17 miles) per second. Mercury and Venus are closer to the Sun, so they take shorter times to make one orbit. Mercury takes only about 88 Earth days to make one trip around the Sun. All of the other planets take longer amounts of time. The exact amount depends on the planet's distance from the Sun. Saturn takes more than 29 Earth years to make one revolution around the Sun. How old would you be if you were on Jupiter?. Q: How many miles is the distance between the earth and sun? Choices: - 91 - 82 - 78 - 93 A:
(A).
93
Ques:Answer the following question given this paragraph: The pressure of gases in the atmosphere is greatest at sea level and decreases rapidly as altitude increases. Q: Where is the pressure of gases in the atmosphere at its greatest? Choices: - stratosphere - core - mountain ranges - sea level A:

Ans:sea level
Ques:Answer the following question given this paragraph: Temperature is a measure of the average kinetic energy of the particles in matter. In everyday usage, temperature indicates a measure of how hot or cold an object is. Temperature is an important parameter in chemistry. When a substance changes from solid to liquid, it is because there was an increase in the temperature of the material. Chemical reactions usually proceed faster if the temperature is increased. Many unstable materials (such as enzymes) will be viable longer at lower temperatures. Q: What is the measure of kinetic energy of the particles in matter? Choices: - energy - precipitation - friction - temperature A:

Ans:
temperature
