Answer the following question given this paragraph: No doubt you already have a good idea of what temperature is. You might say that it's how warm or cool something feels. In physics, temperature is defined as the average kinetic energy of the particles of matter. When particles of matter move more quickly, they have more kinetic energy, so their temperature is higher. With a higher temperature, matter feels warmer. When particles move more slowly, they have less kinetic energy on average, so their temperature is lower. With a lower temperature, matter feels cooler. Q: In physics, what is defined as the average kinetic energy of the particles of matter? Choices: - density - friction - magnetism - temperature A:
temperature

Answer the following question given this paragraph: A pure substance is called an element . An element is a pure substance because it cannot be separated into any other substances. Currently, 92 different elements are known to exist in nature, although additional elements have been formed in labs. All matter consists of one or more of these elements. Some elements are very common; others are relatively rare. The most common element in the universe is hydrogen, which is part of Earth's atmosphere and a component of water. The most common element in Earth's atmosphere is nitrogen, and the most common element in Earth's crust is oxygen. Several other elements are described in the musical video at this URL:. Q: What is a pure substance called? Choices: - a mixture - homogeneous matter - a liquid - an element A:
(Answer)
an element
Ques: Answer the following question given this paragraph: Photochemical smog consists mainly of ozone (O 3 ). The ozone in smog is the same compound as the ozone in the ozone layer,(O 3 ). But ozone in smog is found near the ground. Figure below shows how it forms. When nitrogen oxides and VOCs are heated by the Sun, they lose oxygen atoms. The oxygen atoms combine with molecules of oxygen to form ozone. Smog ozone is harmful to humans and other living things. Q: What dangerous oxygen compound is found in ground level smog? Choices: - argon - sulfur dioxide - neon - ozone A:
Ans: ozone

Answer the following question given this paragraph: Magnetic Field Produced by a Current-Carrying Solenoid A solenoid is a long coil of wire (with many turns or loops, as opposed to a flat loop). Because of its shape, the field inside a solenoid can be very uniform, and also very strong. The field just outside the coils is nearly zero. Figure 22.40 shows how the field looks and how its direction is given by RHR-2. Q: What current-carrying long coil of wire acts as a magnet? Choices: - converter - antenna - igniter - solenoid A:
(A).
solenoid
Ques:Answer the following question given this paragraph: Anal Canal Finally, food residue reaches the last part of the large intestine, the anal canal, which is located in the perineum, completely outside of the abdominopelvic cavity. This 3.85 cm (1.52 in) long structure opens to the exterior of the body at the anus. The anal canal includes two sphincters. The internal anal sphincter is made of smooth muscle, and its contractions are involuntary. The external anal sphincter is made of skeletal muscle, which is under voluntary control. Except when defecating, both usually remain closed. Q: In humans, the anus is attached to what kind of intestine? Choices: - huge - internal - small - large A:

Ans:large
Answer the following question given this paragraph: Any organic material can be made into electricity. But some materials are better than others. Wastes can be used, like almond shells. Biomass power is a great use of wastes. It's hard to use wastes as a consistent large scale source of energy though. Q: What kind of material that might otherwise go to a landfill can serve as the source of biomass power? Choices: - mechanical waste - microscopic waste - reactive waste - organic waste A:
organic waste
