At point A, as shown in the figure below, is a clockwise line vortex of strength K = 12 m2/s. At point B is a line source of strength m = 34 m2/s. Determine the resultant velocity induced by these two at point C. Round the answer to two decimal places

To generate the data shown at the right, the dipole magnet was moved closer to the sensor (holding for 10-20 seconds at each distance). The magnet was then moved back away from the sensor in a similar fashion. This provided two data points at each distance (except the closest) to be averaged. Each data point was corrected for the background magnetic field measured at 0.5 meters (no change observed at longer distances). The absolute values of the corrected field are given in the table.Use the data provided below to determine the dependence of the magnetic field on distance, based on a linear trendline.

Calculate the magnetic flux through a square of length 1.9 cm, if the magnetic field is 2.5x10-5 T and the loop is oriented at an angle of 40.00 to the magnetic field. Submit your answer in exponential form with correct number of significant digits. You are required to show your work in the file you submit.

Coul you please include an explinantion for the right answer?  I don't understand what the question wants.
