1.)two objects, one of m=20,000 kg, and another of 12,500 kg, are placed at a distance of 5 meters apart. what is the force of gravitation between these two objects? 2.) if the two objects in the previous question are moved so that the distance between them is cut exactly in half to 2.5 m, what is the new value of the force between them? 3.) if a perpendicular force is applied to an object at 0.5 m from the radius, causing it to rotate, what is the torque if the force is 25 n? 4.)a hoop that has a moment of inertia (i) of 0.007875 kg*m^2 and an angular velocity of 6.28 rad/s has what value for angular momentum (l)?
