Question

the image shows a speaker plugged into a socket. what type of energy transformation is happening? a) electrical to sound b) radiant to electrical c) chemical to thermal d) mechanical to sound

Explanation:

A speaker plugged into a socket uses electrical energy (from the socket) and converts it into sound energy (produces sound). Radiant energy is related to electromagnetic waves (like light), chemical energy is stored in substances (e.g., in batteries), and mechanical energy is related to motion or position. Since the input is electrical (from the socket) and output is sound (what the speaker does), we check each option.

• Option A: Electrical (from socket) to sound (speaker's function) - correct.
• Option B: Radiant to electrical - no radiant input here.
• Option C: Chemical to thermal - no chemical input, no thermal output (speaker's main output is sound).
• Option D: Mechanical to sound - no mechanical input (input is electrical from socket).

Answer:

A. electrical to sound
