Answer:
d. The buoyant force on the rock is constant as it sinks.
Explanation:
The sinking of an object in water can be explained by the Archimedes Principle.
The Archimedes principle states that the buoyant force on a submerged substance is equal to the water displaced by the submerging object. The buoyant force, however, does not change with depth as the substance sinks.
In the given question, when the rock moves beneath the pool, the buoyant force do not change and remains the same that is the amount of water displaced by rock remains the same.
Thus, Option-D is the correct answer.
Answer: S<span>peed = 60.11 miles per hour

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.
<span>speed = distance/time</span>
Hi there!
We can use the following relationship between the Potential Difference and the Electric field:
V = Potential Difference (500V)
E = Electric Field (V/m)
d = separation between plates (0.2 m)
We can rearrange the equation to solve for the electric field:
Plug in the given values.
