Answer 1

24. Option C. The energy released during fusing or splitting of atomic nuclei is nuclear energy. It is also known as nuclear binding energy. This is the energy required to keep the protons and neutrons of nucleus intact and this is released in both the processes.

25. Option B. An electric guitar is the obvious answer as it converts electric energy to sound. The other options would convert electric energy to heat as happens in the cooker microwave and iron.

26. Option C. Electric energy can be produced through various other means such as coal, natural gas, nuclear power etc. All other options are correct except this.

27. Option C. Potential energy isthe energy an object possesses when it is lifted to a height above zero height.
