determine the time it takes for a satellite to orbit the earth in a circular near-earth orbit. a near-earth orbit is one at a height above the surface of the earth which is very small compared to the radius of the earth.

be subject to a force andchange its motion

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.

gravitational energy

electrical energy

kinetic energy

ligh energy
