Two long parallel wires separated by 0.0350 m and the first wire carries 4.70 A. The magnetic field is zero between the two wires at a position 0.0130 m from the first wire. What is the current through the the second wire

The earth remains in orbit around the sun due to the force of gravity. how does the force of gravity exerted by the sun on the earth compare to the force of gravity exerted by the earth on the sun?

What property of an object determines its inertia?

The path of a satellite orbiting the earth causes it to pass directly over two tracking stations a and b, which are 51 miles apart. when the satellite is on one side of the two stations, the angles of elevation at a and b are measured to be 87 degrees and 84 degrees, respectively. (a) how far is the satellite from station a? (b) how high is the satellite above the ground?
