This statement about the potential due to the sphere is correct: THE POTENTIAL IS HIGHEST AT THE CENTER OF THE SPHERE.
The potential is highest at the center of the sphere because, charge usually flow from the region of higher potential to lower potential.
Answer:
decrease the area in the second cylinder
Explanation:
In a two-cylinders pneumatic system, the pressure exerted on the first cylinder is equal to the pressure on the second cylinder:

We can rewrite the pressure as product between force (F) and area (A) of the cylinder:

In this system, the output force should be 4 times the input force:

Substituting into the previous equation, we get:

This means that the area of the second cylinder must be 1/4 of the area of the first cylinder, so the correct answer is
decrease the area in the second cylinder
This is an example of kinetic to potential because the water is moving, pushing a turbine (Kinetic) and the turbine converts the energy to potential energy.
Answer:
Explanation:
still water speed is 50 m / 25.0 s = 2.00 m/s or 200 cm/s
In lane 1 the effective speed would be 201.2 cm/s
5000 cm / 201.2 cm/s = 24.85 s
The change is 25.00 - 24.85 = 0.15 s decrease in time
In lane 8, the effective speed would be 198.8 cm/s
5000 cm / 198.8 cm/s = 25.15 s
The change is 25.00 - 25.15 = 0.15 s increase in time
