Which best explains how an object at rest deep in space and far from any massive body behaves compared to an object in free fall in earth’s gravitational field?
they behave differently because, according to the principle of equivalence, the laws of physics depend on frames of reference.
they behave differently because, according to gravitational redshift, the laws of physics depend on frames of reference.
they behave the same because, according to the principle of equivalence, the laws of physics work the same in all frames of reference.

Currents in dc transmission lines can be 100 a or higher. some people are concerned that the electromagnetic fields from such lines near their homes could pose health dangers. for a line that has current 150 a and a height of 8.0 m above the ground, what magnetic field does the line produce at ground level? express your answer in teslas and as a percentage of the earth’s magnetic field, which is 0.50 g. is this value cause for worry?
