A tractor pulls a trainer at a constant speed the tractor exerts a forward force of 1600N on the trailer. What is the force exerted by the trailer on the tractor?

Electoral current force mechanical advantage if the wheel and axle is 2 n and the output force is 20 n

Answerthe force between the charges will be  f/9 (one-ninth of force f)explanationcoulomb's law relates the magnitudes  two point charges q₁ and q₂, the distance, r, between the charges, and the electrostatic force, f, between the two charges:     k represents coulomb's constant, k = 8.99×10⁹ n·m²/c².note that if we have r = 3r, then
