Q: Wave amplitude of a transverse wave is the difference in height between what and the resting position? Read this paragraph and choose the correct option from the provided answers: Wave amplitude of a transverse wave is the difference in height between a crest and the resting position. Wave amplitude of a longitudinal wave is the distance between particles of the medium where it is compressed by the wave. Choices: - a valley - a cascade - a magnitude - a crest A:
(Answer)
a crest

Ques: Q: A turbine that spins a generator will produce? Read this paragraph and choose the correct option from the provided answers: You can follow the operation of an electricity-generating fission reactor in the image above. The reactor core is submerged in a pool of water. The heat from the fission reaction heats the water, which is pumped into a heat exchange container. There the heated water boils the water in the heat exchanger. The produced steam is forced through a turbine that spins a generator and produces electricity. After the water passes through the turbine, it is condensed back to liquid water and pumped back to the heat exchanger. Choices: - solar energy - light - magnetic fields - electricity A:
Ans: electricity

(Q).
Q: Structures that have lost their use through evolution are called _______ Read this paragraph and choose the correct option from the provided answers: Some of the most interesting kinds of evidence for evolution are body parts that have lost their use through evolution ( Figure below ). For example, most birds need their wings to fly. But the wings of an ostrich have lost their original use. Structures that have lost their use through evolution are called vestigial structures . They provide evidence for evolution because they suggest that an organism changed from using the structure to not using the structure, or using it for a different purpose. Choices: - primordial structures - residual structures - symbiotic structures - vestigial structures A:
(A).
vestigial structures

Ques:Q: How many watts equals a horse power? Read this paragraph and choose the correct option from the provided answers: Sometimes power is measured in a unit called the horsepower. For example, the power of car engines is usually expressed in horsepowers. One horsepower is the amount of work a horse can do in 1 minute. It equals 745 watts of power. Compare the horsepowers in the Figure below to the other Figure below . Choices: - 695 - 904 - 375 - 745 A:

Ans:745

Q: How can you prevent your ice cream from getting a sandy texture? Read this paragraph and choose the correct option from the provided answers: Fructose, a sugar found in fruit, contains only carbon, oxygen, and hydrogen. It is used in ice cream to prevent a sandy texture. Complete combustion of 32.4 mg of fructose in oxygen produced 47.6 mg of CO2 and 19.4 mg of H2O. What is the empirical formula of fructose? 11. Coniine, the primary toxin in hemlock, contains only carbon, nitrogen, and hydrogen. When ingested, it causes paralysis and eventual death. Complete combustion of 28.7 mg of coniine produced 79.4 mg of CO2 and 34.4 mg of H2O. What is the empirical formula of the coniine? 12. Copper and tin alloys (bronzes) with a high arsenic content were presumably used by Bronze Age metallurgists because bronze produced from arsenic-rich ores had superior casting and working properties. The compositions of some representative bronzes of this type are as follows:. Choices: - by using lowfat milk - by adding oil - by adding salt - by using fructose A:
by using fructose
