bjects 1 and 2 attract each other with a electrostatic force 36.0 units. If the charge of Object 1 is one-third the iginal value AND the charge of object 2 is doubled AND the distance separating Objects 1 and 2 is doubled, then the new electrostatic force will be units.​

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

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.
