What forms of energy does an electric-powered lawn mower utilize? Which of the following is/are valid options? Thermal, Chemical, or Radiant.
An electric-powered lawn mower utilizes primarily electrical energy to operate. It draws power from an electrical source, usually the electricity grid or a battery, to run an electric motor that drives the machine's cutting blades.
To determine which of the given options - thermal, chemical, or radiant - can be associated with an electric-powered lawn mower, we can examine the characteristics of these forms of energy:
1. Thermal energy: This form of energy is associated with heat. In the case of an electric-powered lawn mower, it does not directly utilize or produce heat, so thermal energy is not a valid option.
2. Chemical energy: This energy is associated with the potential energy stored in chemical bonds. While batteries store chemical energy and are often used to power electric lawn mowers, the lawn mower itself does not directly utilize or produce chemical energy during its operation. Therefore, chemical energy is not a valid option for an electric-powered lawn mower.
3. Radiant energy: This form of energy refers to the energy of electromagnetic waves, such as light or heat. While an electric-powered lawn mower may emit some radiant energy in the form of heat or sound during its operation, it is not a primary energy source for the mower. Therefore, radiant energy is not a valid option either.
In summary, an electric-powered lawn mower primarily utilizes electrical energy, and none of the given options - thermal, chemical, or radiant energy - are considered valid sources of energy for an electric-powered lawn mower.
