Final Answer:
The force responsible for suspending the 9 kg rock in question 7936 is b) Tension force.
Step-by-step explanation:
In this scenario, the force that acts on the 9 kg rock to keep it suspended is tension force.
Tension force occurs when an object is pulled or hung by a rope, cable, or any other similar material.
In the case of the rock, a rope or some form of support is holding it in place, and the tension force within that support counteracts the force of gravity pulling the rock downward.
Tension force is a common concept in physics, especially when dealing with objects in equilibrium or when there is a need to balance gravitational forces.
It is crucial to understand the forces at play in situations like this to analyze and predict the behavior of objects under various conditions.
In summary, the correct answer is b) Tension force, as it is the force that counteracts gravity and keeps the 9 kg rock suspended in question 7936.
