Charge q experiences a repulsive force of 0.50 mN when placed at a distance of 25 cm from charge q_1, and it experiences an attractive force of 0.25 mN when placed a distance of 75 cm from charge q_2. The ratio q_1/q_2 is

The car would move to the right with 150 n of force. the 150 n of force from friction and air resistance slows the car from moving to the right with 300 n of force.

"induction" is the process of charging an object without touching it.hope my answer has you : )

The chemical reactions lab we did is typically called a "copper plating lab,  because the acid solution cleaned the pennies and made the copper look shinier;   the acid solution cleaned the paperclips and made them look like pennies;   &   the copper from the pennies was removed, and then added to the paperclips.
