Answer: I think the current produced by different types of magnets
Explanation:
Weight of the mass is the tension in the string if the turntable is held fixed, with the mass hanging from the pulley
Weight is a force that acts at all times on all objects near Earth. The Earth pulls on all objects with a force of gravity downward toward the center of the Earth. Weight (symbolized w ) is a quantity representing the force exerted on a particle or object by an acceleration field, particularly the gravitational field of the Earth at the surface.
The tension force is defined as the force that is transmitted through a rope, string or wire when pulled by forces acting from opposite sides. The tension force is directed over the length of the wire and pulls energy equally on the bodies at the ends.
The direction of tension is the pull which is given the name tension. Thus, the tension will point away from the mass in the direction of the string/rope. In case of the hanging mass, the string pulls it upwards, so the string/rope exerts an upper force on the mass and the tension will be in the upper side.
Tension will act opposite the the weight of the mass attached in order to maintain equilibrium .

Answer:
The speed of the stone when it is 4.66 m higher is 236.057 m/s.
Explanation:
Given the initial velocity and vertical distance, we can use the fourth kinematic equation (
) to find v final, or the v to the left of the equal sign. We know 
(initial velocity) is 24.7 m/s, y (change in vertical distance) is 4.66 m, and a is another way to write g (acceleration due to gravity), or 9.8 
.
From here you could plug in the values and solve for v final, but to make the solving process simpler, we can simplify the given equation, <em>then </em>plug in the known values.
To isolate v final, we can take the square root of 
and do the same to the right side of the equation. Therefore, we can find v final with: 
, where v initial is outside of the square root because it squared...
If we plug in the known values to the simplified equation, we get: 
The final answer is 236.057 m/s.
C did the most effort, but A walked the longest, so a reasonable answer is that they all did the same amount of work, as B simply mediates.
