Question

question 14 of 20 : select the best answer for the question. 14. which effect is used in a turbine to convert mechanical energy into electricity? a. nuclear fission b. electromagnetic induction c. photosynthesis d. coalification mark for review (will be highlighted on the review page) << previous question next question >>

Explanation:

• Option A: Nuclear fission is the splitting of atomic nuclei to release energy, not related to turbine electricity generation from mechanical energy.
• Option B: Electromagnetic induction is the process where a changing magnetic field (from turbine's mechanical motion) induces an electric current, which is how turbines convert mechanical energy to electricity.
• Option C: Photosynthesis is the process in plants to convert light energy to chemical energy, irrelevant here.
• Option D: Coalification is the process of forming coal, not related to energy conversion in turbines.

Answer:

B. Electromagnetic induction
