A submarine dives down to a depth 80 metres beneath the surface of the ocean.
Calculate the pressure in atmospheres at that depth, assuming the density of water
is 1029 kg/m3, and the air pressure at the surface is 105.2 kPa. Give your answer
with two digits of precision.
Note: 1 standard atmosphere is 101325 Pa.

Answer
"A standard 1 kilogram weight is a cylinder 48.5 mm in height and 44.5 mm in diameter. What is the density of the material in kg/m^3 ?"I keep trying this problem and it's just a practice problem and the program is telling me the answer is 13300 kg/m^3, but I'd like to see it worked out in full so I can figure it out for myself. My answers are similar so I think I might just be making rounding errors.
The density of the atmosphere varies drastically with height, but you can use an average
density from sea floor to the space in order to calculate its height. If we approximate this
average density to be = 1 Kg/m³, what would be height of the atmosphere?
HINT: Since the atmosphere is a fluid (in gas form), you can use the hydrostatic pressure
formula (P
pgh), just solve for h and use P = 1 atm.
BTW, this is how the edge of space is defined, if you make it pass the height of the
atmosphere you have reached space :)

Use the barometric law (2.81) to calculate the mean altitude of the surface above sea level.b. Calculate the total mass of the atmosphere by considering that Force = Pressure * Area. The downward force of the atmosphere, by Newton’s Law, is the mass of the atmosphere times the acceleration of gravity.

- You are working for a window-manufacturing company. The company has just landed a new contract for homes being built in Alaska. There is some concern about the windows surviving in an area where fierce hailstorms occur with some regularity. Because of strong horizontal winds, the hailstones often fall at an angle of 0 = 45.0° to the ground. Measurements have been made during such winds with the following typical results: hailstones strike vertical surfaces at an average rate of 2,200 per minute per square meter of vertical surface. The hailstones have an average mass of m= 5.00 g and an average speed of v = 7.70 m/s.
