. A plastic spherical balloon is held below the surface of a swimming pool by a cable tied to the bottom of the pool. The sphere has a volume of 1.50 x 10 -2 m 3 and the tension in the cable is 90.0N. What is the buoyant force exerted by the water on the sphere? 147N
A cabel is pulling a box with mass 300 kg on a horizontal plane. The cabel acts 60
on the direction of movement of the box. If the tension in the cabel is 1000 N and
the box is moved for 4.5 m, calculate the work done to move the box.
