ror penguins dive deeper into sea water than any other bird. An Emperor penguin weighing 245 newtons [N] can dive to a maximum depth of 450 feet [ft] below the surface of the sea water. The volume of an Emperor penguin can be modeled as a cylinder with a diameter of 0.25 meters [m] and a height of 1.1 meters [m]. The specific gravity of sea water is 1.027. Find the total pressure acting on the penguin at the maximum depth in units of atmospheres [atm

NASA sent a probe to Saturn's moon Titan, where the acceleration due to gravity is 1.4 meters per second squared [ms2]. Titan's atmospheric pressure is 1.3 times Earth's atmospheric pressure at sea level. The probe landed in a lake of liquid methane, which has a density of 0.454 kilograms per liter [kgL]. Since the probe weighs 300 pounds-force [lbf] on Titan and has a volume of only 1.2 cubic feet [ft3], it immediately sank. It now sits 65 feet [ft] below the surface of the lake. The lake has a surface area exposed to the atmosphere of 24500 square meters [m2]. What is the total pressure exerted on the probe, in pascals [Pa]?

If the pressure is 180 pounds per square inch [psi], what is the pressure in units of feet of water [ft H2O]?

Given the figure, if the tensile stress on the rod is 32.6 [kPa], what is the mass of the block?

If the bottom pressure is 1.27 [Kg/cm2.abs], find the height of the liquid with a density of 0.642 [g/cm3]. The upper side is open to the atmosphere.

Assume the following objects are pushed with a force such that they all accelerate at the same rate of 150 meters per second squared [ m / s 2. Determine which object requires the greatest force to accelerate at this rate. Cricket ball , mass = 0.35 pound - mass [ lb m ] Hockey puck , mass = 17 decagrams [ dag ] Soccer ball , mass = 4000 decigrams [ dg ] Rugby ball , mass = 0.031 slu
