A steady 3.0-lb force is applied normal to the handle of the hand-operated grinder. The gear inside the housing with its shaft and attached handle together weigh 3.56 lb and have a radius of gyration about their axis of 2.75 in. The grinding wheel with its attached shaft and pinion (inside housing) together weigh 1.09 lb and have a radius of gyration of 2.22 in. If the gear ratio between gear and pinion is 7:1, calculate the speed N of the grinding wheel after 7 complete revolutions of the handle starting from rest.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
