Answer:
The average speed is 60 miles per hour or 1 mile per minute.
Explanation:
If you multiply 30 by 2 to find the miles per hour, you also have to multiply 30 miles by 2. This results in 60 miles per hour. If you want to find the miles per minute, you divide the 30 minutes by 30. You have to do the same to the miles, so the average speed could also be 1 mile per minute.
Answer: 1. High, low. 2. Decreasing, increasing. 3. Nothing, highest. 4. Kinetic, thermal. radio plays- Back at home, you turn on a radio It runs on electrical energy which travels along the wires that connect a power plant to your home. The electrical energy used by the radio is converted into sound energy. Sound is another form of kinetic energy--it's air in motion. eat dinner- Back at home, you turn on a radio It runs on electrical energy which travels along the wires that connect a power plant to your home.

Radiant heaters emit infrared radiation into the room that directly heats objects and people who are close to them. One way to generate electricity is to burn solid waste, like the material found in landfills. ... That thermal energy is transformed into electrical energy, usually by turning a turbine. Another energy resource that comes from our garbage is the methane gas that is produced as the waste decays. A television set is another device that operates by the transformation of energy. An electrical beam from the back of the television tube strikes a thin layer of chemicals on the television screen, causing them to glow. In this case, electrical energy is converted into light.
