Science Final Exam Practice

Which of the following is a major drawback of nuclear energy for generating electricity?

• Destruction of plants and land areas

• Emission of acid rain-causing gases

• Generation of radioactive waste

• Greenhouse gases leakage into the environment

What is the likely environmental impact of extracting coal from the earth?

• Disposal of radioactive waste

• Loss of natural habitats due to land clearing

• Chemical leakage from pipelines

• Formation of acid rain

One of the main problems caused by fossil fuel combustion in power plants is:

• Greenhouse gas buildup in storage tanks

• Emissions of pollutants leading to environmental damage

• Forest loss from infrastructure expansion

• Solid waste requiring special disposal

A common risk associated with natural gas transport through pipelines is:

• Leakage

• Nuclear pollution

• Soil erosion

• Industrial noise pollution

What is the distance from the top of one wave (crest) to the top of the next wave called?

• Amplitude

• Frequency

• Wavelength

• Wave height

What do we call the height of a wave from the middle line up to the top (crest)?

• Wavelength

• Amplitude

• Period

• Speed

Which tells how many waves pass a point in one second?

• Frequency

• Wavelength

• Amplitude

• Trough

If waves are close together (short crest-to-crest distance), what can we say about the frequency?

• It is low

• It is high

• It stays the same

• It disappears

What type of wave is this, and what is the direction of particle motion compared to the wave direction?

• It is a longitudinal wave; particles move up and down, which is perpendicular to the wave direction.

• It is a longitudinal wave; particles move back and forth, which is parallel to the wave direction.

• It is a transverse wave; particles move up and down, which is perpendicular to the wave direction.

• It is a transverse wave; particles move back and forth, which is parallel to the wave direction.

Point B in the diagram is referred to as

• Crest

• Trough

• Rarefaction

• Compression
