A 12.0 kg block of metal measuring 12.0 cm by 10.0 cm by 10.0 cm is suspended from a scale and immersed in water as shown in the figure below. The 12.0 cm dimension is vertical, and the top of the block is 4.15 cm below the surface of the water. Scale i (a) What are the magnitudes of the forces (in N) acting on the top and on the bottom of the block due to the surrounding water? (Use Po = 1.0130 × 105 N/m². Enter your answers accurate to at least four significant figures.) Ftop N = N = Fbottom (b) What is the reading of the spring scale (in N)? N (c) Show that the buoyant force equals the difference between the forces at the top and bottom of the block. (Submit a file with a maximum

A lobster tank in a restaurant is 0.75m0.75m long by 0.5m wide by 40cm deep.Taking the density of water to be 1000kg/m^3, find the water forces on the sides of the tank. (I already did the first part but need help with the rest)

Calculate the contact angle (in degrees) for olive oil if capillary action raises it to a height of 7.05 cm in a glass tube with a radius of 0.100 mm. O Is this value consistent with that for most organic liquids? No. The contact angle is nearest to the value for water-silver. Yes. The contact angle is nearest to the value for most organic liquids-glass. No. The contact angle is nearest to the value for kerosene-glass. No. The contact angle is nearest to the value for mercury-glass. 0000

A length of clear plastic tubing is bent into a vertical U, as shown in the figure, and two liquids that do not mix are poured into it. Liquid A, with density ρA continues from the left column into the right. Its height is d1 in the left column and d2 in the right column. Liquid B, with density ρB, sits on top of liquid A in the right column. Its height is d3 above liquid A. a) Enter an expression for the density of liquid B, in terms of the other defined quantities.  b) Calculate the density of liquid B, in kilograms per cubic meter, if liquid A has a density of ρA = 1.6×103 kg/m3, and d1 = 11.8 cm, d2 = 7.2 cm, d3 = 6.3 cm.
