A student drops a book to the floor to investigate how energy changes into sound. When the book hits the floor, it makes a loud sound. How was the sound produced?
Electrical energy was produced when the book hit the floor. This produced a sound.
Energy of motion from the falling book was converted to heat. The heat produced a sound.
Electrical energy was produced as the book fell to the floor, which caused a sound to be produced.
Energy of motion from the falling book was transferred to the floor, which caused a sound to be produced.
Which of the following is not a source of energy?
Fossil Fuels
Wind
Sun
Solar Panel

By putting it in the shade
By turning it off
Which is the best argument in favor of using the solar cooker?
Solar cookers get hotter than electric ovens.
Solar cookers are easier to use than electric ovens.
Solar cookers are more reliable than electric ovens.
Solar cookers are better for the environment than electric ovens.
Which statement provides the best evidence for the benefits of cooking with a solar oven?
Solar cookers are powered by the sun, which makes them much easier to control than electric ovens.
Solar cookers are powered by wind energy instead of gas. Wind energy is a renewable and clean energy source.
Solar cookers are powered by gas instead of energy from the sun. Unlike energy from the sun, gas is a renewable source of energy.
