Question

In a washing machine, the electrical energy is converted into_____

• A. mechanical energy
• B. sound energy
• C. kinetic energy
• D. chemical energy

Answer 1

Answer: (A), (C)

kinetic energy

1. Mechanical energy is the energy possessed by a body due to its position or motion.
2. Sound energy is that form of energy that enables us to hear.
3. Kinetic energy is the energy of a body due to its motion.
4. Chemical energy is the energy released during the formation of bonds between atoms.

Here, a washing machine takes electric energy and converts it into kinetic energy (as the machine rotates), and kinetic energy is a type of mechanical energy.

Hence, option (a) and option (c) both are correct.
