Answer: MAGNITUDE AND DIRECTION OF A VECTOR
Explanation: Given a position vector →v=⟨a,b⟩,the magnitude is found by |v|=√a2+b2. The direction is equal to the angle formed with the x-axis, or with the y-axis, depending on the application.
In general, when designing the experiment, it is desirable to control all thing that can affect the outcome of the experiment. In practice, this is not easily obtainable.
I imagine it would be hard to control the temperature in this experiment. Even though, temperature does affect the ball's bounce.
Keep in mind that even if you don't control something it still can be measured and then you can use that information to correct your predictions.
Answer:
(C) line integral along a closed loop
This integral is evaluated by dividing the path into infinitesimal segments dL, calculating the scalar product B•dL for each segment, and sum these products. The component of B parallel to dL at each point is always used in evaluating this integral.
The line integral is equal to mu_o × I.
