Question

Buoyancy problem

Answer 1

You find a job as part of a team doing oceanic research. The team is going to monitor water
temperature, salinity, Ph, etc. To do this, the team is going to use an instrument package contained in
a hollow, aluminum sphere. The aluminum sphere has an outer diameter of 1.00 m and a thickness of
1.00 mm. (Use 2.70 g/cc for the density of the aluminum) The aluminum sphere will be supported by
a tether connected to a solid Styrofoam sphere that is also of 1.00 m diameter. (Use 300.0 kg/m3 for
the density of Styrofoam)

Answer 2

calculate the maximum weight that is allowed before the whole thing sinks
I know the density of aluminum in kg/m^3 is 2700 and the density of seawater is 1027, where would i start

Answer 3

maximum weight of the instrument
