A crane is used to lower rectangular concrete blocks (0.4 m × 0.4 mx 0.3 m) into the ocean so that they can be used as weights for an underwater construction project. a. Determine the tension in the rope of the crane (in N) when the concrete block is not moving and fully submerged in seawater (at 20 °C). b. Determine the percentage by which the tension in the rope increases when the concrete block is not moving and instead suspended in air (at 10 °C).

The gravitational force exerted on a solid object is 5.25 N as measured when the object is suspended from a spring scale as in Figure a. When the suspended object is submerged in water, the scale reads 3.98 N (Figure b). Find the density of the object. kg/m3 Scale B MgV
Pressure cookers use water at very high pressures to cook food very quickly. They have been around for more than 300 years, although their use has strongly declined in recent years (early models had a nasty habit of exploding). a. How much force, in newtons, must the latches holding the lid onto a pressure cooker be able to withstand if the circular lid is 27.5 cm in diameter and the gauge pressure inside is 0.95 atm? Neglect the weight of the lid.
