CAN ANYONE PLEASE HELP ME WITH THIS??? 3 long straight wires are mounted on the verticies of an equilateral triangle as shown on the figure. The wires carry currents of I1 = 6.50 A, 12 = 8.50 A, and I3 = 5.50A. Each side of the triangle has a length of 24 cm and the point A is located halfway between I1 and I2 along one of the sides. Find the magnitude of the magnetic field at point A.

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
