Which of these systems is NOT an ""isolated system"" to which conservation of momentum can be applied?1. A billiard ball collides with another billiard ball on a level pool table. (Ignore friction with the table during the instant of the collision.) System: the two balls2. A ball falls freely toward the ground. (Ignore air friction.) System: the ball and the earth3. All of these in fact are isolated systems.4. A single car slips on an icy road. (Friction with the ice is negligible.) System: the car5. Two cars slipping on an icy road collide with one another. (Friction with the ice is negligible.) System: the two cars6. A ball falls freely toward the floor. (Ignore air friction.) System: the ball7. Two masses connected by a spring oscillate on a frictionless tabletop. System: the two masses and the spring

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.
