The acceleration of the moon is about 1/3600 of the acceleration of objects falling on earth, which confirms Newton’s view that the same force that makes objects on the surface of the earth fall, keeps the moon in orbit, because the moon is about 60 Earth radii from the Earth. True

Or

False?

a displacement distance is size of displ

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.
