What kind of energy transformation is represented in the system above?
Mechanical-> Electrical-> Light
Light-> Electrical-> Light
Light->Electrical-> Sound
Light->Chemical-> Electrical-> Sound
It is a cold day. Tom decides to turn on the heat in his home. His home is connected to power lines that eventually receive their power from a hydroelectric dam about 50 miles away. What energy transformations allows tom to heat up his home?
Mechanical energy from the river turns into electrical energy in the dam. This electrical energy flows to Tom’s home which in return makes him turn on the ac which releases chemical energy.
Mechanical energy from the river to Chemical energy in the dam. This chemical energy flows to Tom’s home which in return makes him turn on his heater, which releases heat energy to warm up his home
Mechanical energy from the river to electrical energy in the dam. This electrical energy flows to Tom’s home and allows him to turn on the heater, which transforms electrical energy to heat energy
An earthquake seeds out mechanical waves in all directions. These waves travel through different materials in the Earth. Properties of a wave change when it moves from one material to another. What property of a wave changes as it moves from one material to another
Wave speed
Wavelength
Wave frequency
Wave amplitude
During a thunderstorm, you see the lighting before you hear the thunder. Which of the following explains this observation?
Light travels faster than sound
Light has a greater mass than sound
Sound has a longer wavelength than light
Sound and light travel at the same speed
Visible Light and Gamma Rays do not need a medium to travel from one place to another. Visible light and Gamma rays are examples of:
Electromagnetic Waves
Mechanical Waves
A wave light is traveling from the air to water. What will happen to the speed of the light as it travels from one medium (Air) to the other medium (water)?
The light will speed up when it hits the water
The light will slow down when it hits the water
The speed of the light will remain the same
Identify which property of a wave is labeled F
Period
Frequency
Amplitude
Wavelength
