What is the weight, to the nearest tenth of a Newton, of
an iron sphere with a radius of cm?






In problem 1) what would be
its apparent weight when immersed in water? 





Water circulates throughout a house in a hotwater heating
system. The water is pumped at a speed of .7 m/s through a cm
diameter pipe in the basement under a pressure of 3 atm. What is the
pressure, to the nearest N/m^2, in a 2 cm pipe on the second floor 5 meters
above the basement? 





In problem 3) what is the velocity,
to the nearest tenth of a m/s, in a 2 cm pipe on the second floor 5 meters
above the basement? 





If the basement pipe is 4 cm
in diameter and the water velocity is .8 m/s, what is the flux of the
outflow, to the nearest tenth, of a liter/s at a cm
diameter faucet on the second floor? 





If wind blows at m/s
over your roof, which has an area of 300 m^2, to the nearest N/m^2, what is
the pressure above the roof(assume that the pressure in the house is 1 atm)? 





In problem 6) what is the
lifting force, to the nearest Newton, on the roof? 





Given that the Bulk modulus of water is 2x10^9 N/m^2 ,what
is its density in units of 10^3 kg/m^3 (to 2 decimal points) at a depth of km?






A kg
lead sphere is immersed in a liquid where it has an apparent mass of 10kg.
What is its radius, to the nearest tenth of a cm ? 





In problem 9) to the nearest kg/m^3, what is the density
of the liquid?
