Physical Science Part 2: Exothermic, Energy sources

By Marie Greene

Multiple Choice

The figure shows the range of electromagnetic energies known as the electromagnetic spectrum. Each part of the spectrum is characterized by its own wavelength and frequency. A key feature of the spectrum is that the higher the frequency the greater the energy. What is the most energetic part of the electromagnetic spectrum?

• microwaeves

• gamma rays

• visible light

• radio and tv waves

• x-rays

Multiple Choice

What is the least energetic part of the electromagnetic spectrum?

• blue light

• red light

• radio and tv waves

• gamma rays

• microwaves

Multiple Choice

Using the graph, which location has the HIGHEST average maximum monthly temperature?

• Honolulu

• San Francisco

• St. Louis

• Miami

• City V

Multiple Choice

As a child on the swing shown reaches the highest point (A), the swing seems to hesitate an instant before it begins to fall back. This hesitation is repeated at the other arc of the arc (D). How is the energy of this motion expressed in the diagram at the points marked A through D?

• potential, kinetic, potential, kinetic

• kinetic, potential, kinetic, potential

• potential, kinetic, potential, potential

• potential, kinetic, kinetic, potential

• kinetic, kinetic, potential, potential
