5- Two long wires carry currents (I1, I2 = 2.5 A) perpendicular to the plane of paper, as shown in

figure. Find the value of (I1) so that the magnetic field

at (P) is horizontal and find also the magnitude of that

field. If a third long wire is placed at the point (P) and

carries a current of (I3 = 4 A) in direction

perpendicular to the paper (out of paper), find the

force per unit length acting on this wire.

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force

Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?
