A solid metal sphere of volume 0.722 m³ is lowered to a depth in the ocean where the water pressure is equal to 4.02 x 107 N/m². What is the change in the volume of the sphere? The atmospheric pressure is 1.013 × 105 Pa and the bulk modulus of the metal from which the sphere is made is 1.27 x 10¹⁰ N/m². Answer in units of m³. Your response...

The density of water is 1.00 × 10³ kg/m³, and the density of mercury is 1.36 × 10¹ kg/m³. Calculate the absolute pressure på at the bottom of a 0.250-m tall graduated cylinder that is one-fourth full of mercury and three-fourths full of water. Pb = Pa

Given: A woman of m = 51 kg stands on the ice. The contact area between her skate and the ice is A = 0.0061 m2 Express the force that the person exerts on the ice, F, in terms of m and g. You do not need to include the force of the column of air above her.  Calculate the numerical value of F in N.  Express the pressure on the ice from the person P in terms of F and A.  Calculate the numerical value of P in Pa

A group of acrobats forms a human tower, each standing on the shoulders of another acrobat. The acrobats have mass 61.7 kg, 76.3 kg, 65.8 kg, and 52.1 kg. The most massive acrobat is on the bottom. The bottom acrobat’s shoes have a total surface area of 0.0009 m2 on their soles. What is the pressure (in n/m2 exerted by the bottom acrobat on the floor?

A particular table has three identical legs, and the surface area at the bottom of each leg in contact with the floor is 4.00 x 10m?. Assume the legs are uniformly spaced around the table, and the mass of the table is uniformly distributed with respect to the legs. The total mass of the table is 32.7 kg. What is the pressure (in Pa) on the bottom of each table leg (due to the floor alone, ignoring atmospheric pressure)? Pa Need Help? Read it
