CP Submarines on Europa. Some scientists are eager to send a remote-controlled submarine to Jupiter’s moon Europa to search for life in its oceans below an icy crust. Europa’s mass has been measured to be 4.80 × 10 22 kg, its diameter is 3120 km, and it has no appreciable atmosphere. Assume that the layer of ice at the surface is not thick enough to exert substantial force on the water. If the windows of the submarine you are designing each have an area of 625 cm 2 and can stand a maximum inward force of 8750 N per window, what is the greatest depth to which this submarine can safely dive?

A probe on a dwarf planet collects 5 moles [mol] of dust material. The sample, which completely fills a cube with a side length of 4 centimeter [cm], weighs 0.19 newtons [N] on the dwarf planet. The density of the material is determined to be 3160 grams per liter [g/L].Determine the gravity of the dwarf planet in units of meters per seconds squared [m/s2].
The inside of the space shuttle is pressurized to 1.01x105 N/m2 while in deep space (outside pressure = 0). What is the outward force acting on the windshield of the craft if the windshield has a surface area of 0.5 m2?
A legendary Dutch boy saved Holland by plugging a hole in a dike with his finger, which is 1.10 cm in diameter.
(a) If the hole was 1.80 m below the surface of the North Sea (density 1030 kg/m3), what was the force on his
finger?

Your response differs from the correct answer by more than 10%. Double check your calculations. N
(b) If he pulled his finger out of the hole, how long would it take the released water to fill 1 acre of land to a depth
of 1 ft assuming the hole remained constant in size? (A typical U.S. family of four uses 1 acre-foot of water, 1234
m3, in 1 year.)
