Answer :
Final answer:
The tension in the supporting cable for a suspended loudspeaker can be found using principles of equilibrium, resulting in an answer of 172 N. The correct multiple-choice option is (d).
Explanation:
The tension in the supporting cable can be calculated using the principles of equilibrium. In this scenario, for the loudspeaker situation, the force can be determined by considering the forces acting on the loudspeaker.
For the loudspeaker situation discussed, the correct answer would be option letter D, which is 172 N. This is calculated by analyzing the forces acting on the loudspeaker and applying Newton's laws of motion. The correct multiple-choice option is (d).
