longitudinal wave

transverse wave

surface wave

2. During an earthquake, energy that has built up in the earth's crust is released by waves traveling through which type of medium? (Lesson 4.02)

Question 2 options:

the water

the ground

the air

a vacuum

3.Sound, earthquakes, and waves in water are mechanical waves because they require a physical to transport energy. (Lesson 4.02)

Question 3 options:

electromagnetic field

disturbance

medium

location

What are the primary responsibilities of a chemical engineer involved in "r& d"? develop large scale manufacturing operations discover new products and processes training of new chemists determine products needed by consumers

How far is the region from the equator or control climate

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
