In the drawing, the rope and the pulleys are massless, and there is no friction. find
(a) the tension in the rope
(b) the acceleration of the 10.0-kg block.
(hint: the larger mass moves twice as far as the smaller mass.)

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.
